MeeGo Ported To Nexus S [Video]



Developer Steven Troughton-Smith recently managed to run MeeGo OS on Google’s Nexus S phone. He has managed to run it via rootfs image on the internal memory, which means that you don’t have to risk flashing your phone to get it running alongside Android 2.3 Gingerbread.
If you are feeling adventurous, you can give MeeGo a go on your Nexus S. Beware though as not everything is functional at the moment. It is still a work in progress, which hopefully with time will improve.
So if you’re insane enough, you can try it yourself right now…
You will need to build a MeeGo rootfs first, in ext2 format. Use my kickstart as a base, it has a few niceties like adb support (i.e. the only way you can interact with it right now). With your image successfully compiled, copy it to linux/rootfs.ext2 on your Nexus S’ internal memory (completely safe, no flashing required).
My boot.img is here – you will need to use fastboot to boot it (fastboot boot nexuss-meego-boot.img), or you can flash it to recovery if you want to dual boot.
As seen in the photo, you won’t really be able to see anything onscreen, but you can use adb to get a root shell like on any Android device. Poke around, play with it, improve upon it, etc. Actually going much further than this is beyond me unless I can find some talented kernel hackers with Nexus S hardware to test on.
Go nuts!

Verizon to give Unlimited Data Plan Offer to iPhone Customers




Few days ago Wall Street Journal posted the news that Verizon would announce iPhone on their network on 1.11.11.And now Wall Street Journal has another information about the Verizon iPhone ,  as they have mentioned that Verizon will have unlimited data plans for their iPhone buyers.
Verizon Wireless network is the largest wireless network in US and offering an unlimited plan with amazing iPhone devices would again increase the users.This is be interesting how they would offer unlimited data plan as most of the networks like AT&T give option of 200MB or 2GB data plan which is obvious no way near to the unlimited plan.
If this news is true then obviously this is an attempt to attract those iPhone and other smartphone users too who wants to use unlimited data plan on their phones.

Microsoft Working on FaceTime Competitor for Windows Phone 7



Obvious the objective of Microsoft towards Windows Phone 7 would be to match the standards of iPhone in coming years and I think their start is not that bad.Looking at the features if iPhone 4 , one of the newest functionality in it is FaceTime calling which was not available with previous iPhone devices.And now neowin.net mentions that Microsoft is also working on FaceTime competitor for their Windows Phone 7 devices.
Although Steve Ballmer did not mentioned many things about coming update of Windows Phone 7 but Neowin got this information from a key Windows Phone 7 employee who revealed their future plans about the device and soon they will have FaceTime like app for their phone too.
Some would ask why don’t just use the video calling feature of skype rather than working on a different application.But the information source mentioned that FaceTime competitor would “reach beyond the hand of Skype”.Itis also expected front facing camera may become requirement for the Windows Phone 8 devices.We don’t know when the video calling app would come for Windows 7 devices ,maybe it would come with Windows 8.

Untethered GreenPois0n iOS 4.2.1 On Release, 4.2b3 SHSH Blobs Will Not Be Required




Members of Chronic Dev have decided to work on their own untethered solution for iOS 4.2.1 jailbreak, confirms Joshua Hill, one of the members of the team. So Instead of releasing a tethered version (like Redsn0w 0.9.6) of GreenPois0n for iOS 4.2.1 jailbreak, they will work on an untethered solution.
p0sixninja: A lot of people are saying another tethered jailbreak is pointless, I agree. Focusing on getting untethered before release
Joshua was asked if it is the same exploit as the one Comex has been working on, and whether or not it will require SHSH blobs for 4.2b3 like Redsn0w 0.9.7. He said that they are working on their own untethered exploit, and that it will not require SHHS blobs for 4.2b3.
tahu363: @p0sixninja I assume you are talking about Greenpois0n? Are you implementing Musclenerd’s untether or do you have your own?
p0sixninja: @tahu363 we’re implementing our own
Capsfanchad: @p0sixninja I’m assuming “your own” will require 4.2b3 shsh? And thanks for your guys work!
p0sixninja: @Capsfanchad lol no
We don’t know when its arriving, so stay tuned and we will inform you as soon as we find out.

Bluetooth Issues fixed by Redsn0w 0.9.7 Beta 5





The iPhone Dev Team has released yet another update to Redsn0w 0.9.7 jailbreak tool. What th previous betas couldn’t do, this one does. It fixes all sandbox-related issues, including Bluetooth problems on an untethered iOS 4.2.1 jailbreak. Also added is an “anti-piracy plea” note as a warning for those of you who are pirating iOS 4.2 beta 3 firmware.
Also, the Windows version of Redsn0w 0.9.7b5 is also ready, well almost, the only problem is that it is currently painfully slow to use, so the iPhone Dev-Team has decided not to release it until they can fix the performance issues.
There is actually a Windows version of beta5, but it’s excruciatingly slowcompared to the Mac version because it’s forced to use files on your hard drive instead of RAM while it’s processing the very large IPSW images.  It really is very very painfully slow, so we probably won’t be releasing it for testing purposes unless it can be sped up somehow.
Follow the the step by step guide here to learn on how to jailbreak your iPhone, iPad or iPod touch on iOS 4.2.1 using Redsn0w.

Verizon iPhone: All you need to know, seriously [Updated]



Shall we say finally, after all the long run of rumors, Apple and Verizon finally dropping theCDMA version of iPhone. The long winding story will finally ends, (hopefully, crossed your fingers tightly) on Verizon's special media event on January 11th, that's Tuesday. We got you the stitched confirmations after the break.

The Wall Street Journal confirms that the Verizon Media Event on January 11th will feature the long rumored Verizon iPhone.

The largest U.S. wireless carrier will say Tuesday that Apple Inc.'s iPhone will be available to its subscribers, according to a person familiar with the matter.
The Wall Street Journal offers no additional details about when the Verizon iPhone will become available to the public.
To be sure that the event results will surely hit the internet, and we're really makes us feel that this is really Apple related and a definitely BIG announcement  MG Siegler of Techcrunch andJim Dalrymple of Loop Insight—both pretty prolific Apple reporter/writers/bloggers, with some guys at MSNBC, Engadget and others.

Yes we know, there's Gizmodo missing in the list of invited. 

As MG himself notes:
I don't typically get invites directly from Verizon to anything. At least not that I can recall. They usually send those directly to the MobileCrunch and CrunchGear guys. But this invite appears to very specifically be for me - it's non-transferable. Would Verizon send me such an invite unless it was specially about Apple?
Unfortunately due to the iPhone 4 leak, Gizmodo have not received an invitation for the event, it feels like the popular tech site has been blacklisted by Apple, even Gizmodo have a pretty good relationship with Verizon. 
Here's what's key: We're great friends with Verizon. (Hi guys!) We've worked with them for years, and we've been to like every event they've had over the last three years. We haven't gotten an invite. Which is weird. We've reached out to Verizon to see why, exactly, we weren't invited, but we've gotten no comment yet. (Update: Verizon's official response is a big ol' no comment.)
All Things Digital reports that Apple CEO Steve Jobs is likely to be present at Tuesday's media event.

While the appearance isn't 100 percent assured, sources in position to know tell me that, barring any unforseen circumstances, Jobs will likely join McAdam onstage in New York when he announces the addition of the iPhone to its handset line-up.
In the most recent report of WSJ, we can expect the Verizon iPhone to be released by near the end of January according to their source related to the matter.

Now after all, we got few more days, until our wish will gone to reality, yes, bring that CDMA iPhone out!

UPDATE:
Tomorrow Apple and Verizon will break or not the Verizon iPhone, and we got here some new updates that really take our attention. And it's just few hours, hold on.

Smartphones & 4G at CES 2011




This year's CES is a little more special than the previous ones with the onset of 4G. As such, the various mobile phone manufacturers, as well as the carriers waste no time in taking advantage of this potential boom and have made huge announcements in response. What strategies will they do in getting ready for the sudden wave of users trying to get hold of this tech? We'll be trying to get as much as we can and present you with everything you need to know in the 4G wave.

AT&T... getting faster with 4G
AT&T kicked things off with the same was as they did the previous year. They've held a summit that mainly focuses on headlining their plans for the upcoming year, mainly rebranding of its HSPA+ network to 4G -- seeming that they've followed suit to the pressure brought about by other carriers doing the same prior. AT&T has both their HSPA+ as well as their LTE units rebranded to 4G and they're planning to release around 20 in 2011.

Dell "Streaking" to 4G
Dell has provided T-Mobile their first 4G tablet thanks to it's HSPA+ compatibility. The 7-inchStreak 7 has Android Froyo running -- coupled with Dell's own Stage skin. Despite not having the tablet-friendly Honeycomb, Dell sure is banking on this and that would eventually reflect on its price once released.

HTC shooting "Thunderbolts"
Dedicating their releases solely for the US market, HTC announced the Thunderbolt, which is basically an EVO 4G reworked to include an improved display, a kickstand, a loudspeaker and a 700 MHz LTE to replace the current WiMAX support.

They've also announced the EVO Shift 4G -- labelled as the EVO 4G's "little brother" -- finally coming to Sprint. It has a smaller than it's larger name sake, as well as a sliding QWERTY keyboard. They've also reduced production costs by removing the front-facing camera -- so no video calls there. Then there's the Freestyle, targeting even a much lower market bracket than the EVO Shift. It has a 3.2 megapixel camera with 3.2-inch touchscreen.

LG and its "NOVA Display"
Taking a different route from HTC where they just focused on US releases, LG was one of the few manufacturers that bothered to show a European product - the Optimus Black. Though not specifically a 4G device, the 9.2mm tablet could possibly be inserted to the 4G line thanks to its use of the "NOVA Display". LG describes it a as a new type of ultra-bright power-efficient LCD bringing 700 nits of luminance that is on-par or even better than those offered by Super AMOLED displays.

Actual 4G gear comes in the form of the Revolution, fitting for Verizon's LTE network -- containing a 4.3-inch SLCD and a rear camera of 8-megapixels resolution.

Finally, LG gave a teaser of a new tablet for T-Mobile, aptly named "G-Slate". This is supposedly running with Android Honeycomb although other than that, not much information is known.

Motorola, pretty much stealing the show
Yup, Motorola definitely had the audience' attention with its slew of 4G-branded devices. Starting off with the Atrix for AT&T, it has a 1 GHz dual core Tegra 2 processor with 1 GB DDR2 RAM, connectivity through HSPA+, a 4-inch display boasting 960x540 screen resolution with a biometric scanner. What's more is that you can easily dock it with compatible laptop and desktops to turn them into Linux machines containing an Android environment for your apps. 

Then there's the Droid Bionic being offered at Verizon. Although not being able to dock like the Atrix, it's still an amazing gadget to have. It has a 960x540 display and the same processor as with the former. Being offered at the Big Red, it has LTE compatibility for its 4G network. 

Moto has got all covered when they announced their Honeycomb-based tablet, the Xoom, also for Verizon. Containing a 10.1-inch display, it has two 1 GHz cores provided by NVIDIA... that's power. Although it isn't 4G compatible like the rest, you can easily upgrade it to LTE during Q2 of 2011.

RIM and the Playbook... we had it all coming
Sprint has made a partnership with RIM to bring in a 4G-compatible version of the PlayBook, dubbed the "4G PlayBook" (that's a no-brainer, seriously). This is basically RIM's first cellular tablet to be announced by a carrier although it isn't backward compatible with CDMA. You can compensate by hooking it up to your BlackBerry phone or locate a WiFi/WiMAX connection. Sprints plans to have this available in the summer.

Samsung, pushing some boundaries
Pushing in size, Samsung announced a 4.5-inch Infuse 4G using it's upgraded Super AMOLED  Plus display that allows better readability than its predecessor. Although less powerful than the dual-core offerings of Motorola, the device utilizes a 1.2 GHz Hummingbird processor with an 8 and 1.3-megapixel rear and front-view cameras respectively -- all coming to AT&T.

Big Red also had some coming to them with a still unnamed LTE phone, dubbed as the SCH-i520. A 4.3-inch Super AMOLED Plus device, it has an 8 megapixel rear and 1.3 at the front. Other than that, not much is known for this unit (not even the name).

No Honeycomb-compatible tablets were shown by Samsung but they did have the Galaxy Tabfor Verizon upped to LTE support. Add to that a 1.2 GHz processor and a 2 megapixel upgrade with its new 5-megapixel rear camera. Prices still unknown at this time.

Sprint... simply active
Although they haven't made huge announcements like the others, they have some stuff coming in the form of the HTC EVO Shift 4G, the 4G PlayBook (both tacked early on) and a3G/4G MiFi from Novatel.

T-Mobile, insisting that it's 4G!
Aside from the slew of handsets they've announced to be carrying, T-Mobile spent the event making sure that everyone gets the clear idea that it has greatly improved its HSPA+ network, claiming that its 4G. Having 200 million subscribers as of count, they'll be introducing a new 42Mbps connectivity pipe across majority of their HSPA+ network. This allows them to upscale it to 600Mbps in the long run -- totally not relying on LTE to meet high data rates.

Big Red and its announcements
Verizon had its presence known with the multitude of handset announcements coming to them. This, however, will most likely lead up to the eventual reveal of their iPhone.All in all, 2011 is a good year to get into Big Red with their great selection.

Verizon, T-Mobile and AT&T strikes with their best 4G mobile phones and advancement in their network, does it negates each other? Simple enough, we got an intuitive thought of it boils down to your personal preference or how interesting the bundle each carrier will offer in terms of their mobile broadband and mobile phone plans.

Verizon's iPhone: CDMA-only, or CDMA/LTE?




Verizon Wireless is expected to announce Tuesday that it will be selling Apple’s iPhone, but it remains unclear whether the smartphone will be CDMA-only, or will also support Verizon’s evolving LTE network in dual mode.
A dual-mode CDMA/LTE phone would have a potential subscriber base of up to 15 million subscribers this year, more than double the 5 million to 7 million poential users of a CDMA-only version, said Dan Hays, a consultant at PRTM.
Still, Hays thinks that Verizon tomorrow will announce an easier-to-implement CDMA-only iPhone that will ship in four to five weeks. That version would cost about $200 to $250 with a two-year service contract, he predicted.
Macworld will feature live coverage of Tuesday’s Verizon press event beginning at 8 a.m. PT
Verizon announced last week at CES that 10 different smartphones, tablets and other devices that will support LTE by mid-year. Hays, however, said that Verizon still will find that LTE chipsets are not yet widely available and that Apple would not want to risk any problems.
Verizon launched LTE networks in 38 markets in December, and said it expects to roll out the technology nationwide by the end of 2013. LTE supports 5 to 12 Mbit/sec on downloads, about 10 times the speed of what CDMA supports today.
PRTM expects that 5 million to 7 million Verizon iPhones will be sold in 2011, less than the 13 million predicted by other firms because CDMA will impose limits on multi-tasking and global roaming and customers won’t want to break existing contracts, especially with other attractive options for Android and other phones in the Verizon line-up.
“Whether Verizon announces an LTE/CDMA iPhone is the million dollar question,” Hays said in an interview with Computerworld. “They are being quite ambiguous about that, but from what I can tell so far it doesn’t appear to be an LTE-capable device. Apple will jump onto LTE pretty quickly but so far. this device coming on Tuesday doesn’t sound like it’s LTE-capable, and I’m a bit disappointed.”
Even so, a count of 5 million to 7 million would want a CDMA-only iPhone, partly because of concerns about AT&T’s GSM-based network. (For three years, AT&T has held an exclusive on sales of the iPhone in the U.S.). Hays said high-end subscribers from other major carriers will switch to Verizon for this advantage.
Jack Gold, an analyst at J. Gold Associates, said he expects Verizon to announce a dual-mode iPhone for CDMA/LTE, even though most users will fall back to CDMA because the LTE network won’t be complete for more than two years.
Gold also said that estimates of 15 million Verizon iPhone subscribers with CDMA is too high.
“But I am sure they will do very well with the iPhone and it will limit adoption of Android on Verizon to some extent,” he said. If priced correctly, the new iPhone could dampen Android sales, he added.
Ken Dulaney, an analyst at Gartner, said that whatever direction Verizon and Apple take on the radio capability, “this [Verizon iPhone] is a big deal.”
He predicted that many smartphone users who are frustrated with AT&T network service for iPhone will move over to Verizon, including many financial services workers in New York who have been especially critical of AT&T service there.
“There is money out there for this new iPhone on Verizon,” Dulaney said.
“People find money under mattresses to buy lots of things they don’t need right away,” he added. “Just watch how many kids buy $500 Nike shoes when they come out. I have seen 5 million and 10 million estimates for [Verizon iPhone] sales. The number is probably somewhere in the middle. But who cares? The iPhone on Verizon is going to be a big success and for a while many new and re-enlisting users will buy the iPhone and not a BlackBerry or Android device.”

Verizon iPhone could be 4G 'World Phone'




My Saturday blog speculated that the Verizon iPhone likely to be announced Tuesday will be a dual-mode phone, able to connect to both Verizon’s CDMA-based network and with AT&T’s GSM-based technology.
But after reviewing some leaked information and talking to some experts, I’m going to take my prediction even further. I think we will see a 4G LTE ‘world phone” announced at Verizon’s big press event in New York Tuesday.
Macworld will feature live coverage of Tuesday’s Verizon press event beginning at 8 a.m. PT
The Verizon iPhone will be dubbed the “iPhone 4G” by Apple and will support the latest and greatest wireless technology of both the No. 1 and No. 2 wireless carriers in the US-LTE for Verizon and GSM/UMTS HSPA+ for AT&T. Both carriers call their network “4G”, hence the name of the phone.

Killer combo

For Verizon customers the new phone will represent the combination of the country’s fastest 4G network with the most popular phone. Verizon has turned on its superfast 4G LTE service in 39 cities so far, and expects to turn on many more this year.
In cities where LTE is available, internet service would run over Verizon’s LTE network, while voice service will run on Verizon’s 3G CDMA network (which will also be supported in the new phone). In cities where Verizon hasn’t yet turned on LTE, customers will rely on CDMA technology for both voice and internet, similar to the way most Verizon phones work today.

AT&T benefits too

AT&T would get something nice out of the deal too. With the “iPhone 4G” Apple will take the opportunity to upgrade the HSPA radio and chipset in the iPhone 4 to much faster HSPA+ technology. AT&T has dramatically increased the speed and efficiency of its network with its nationwide upgrade to HSPA+ technology over the pas year. It says its HSPA+ network produces data speeds as fast or faster than 4G networks (this is true) so its network and devices should be called 4G, too.

World Phone

The iPhone 4G’s support for GSM-based wireless networks would make it a “world phone”-something Apple has wanted in the device from the beginning. What’s a “world phone”? In contrast to CDMA-only phones, GSM-supporting phones can connect to GSM networks virtually anywhere in the world. GSM technology is used by wireless carriers in most of the world outside the US and by AT&T and T-Mobile in the United States.
Building an iPhone that supports CDMA, LTE and GSM would be a very technologically aggressive move by Apple, but one that would pay dividends well into the future.
Much speculation was started by a video leaked January 5 by a company called Global Parts Direct on Geek.com. The video shows what is said to be the outer shell of the new iPhone, and compares the shell to that of the current iPhone 4. Two aspects of the new shell in particular suggest “4G” and “world phone.”
  1. The new shell design shows a SIM card slot. Since today’s Verizon CDMA phones don’t use SIM cards, the existence of the slot suggests either an LTE phone (LTE phones use SIM cards) or support in the new phone for GSM-based networks, which also use SIM cards. I think it’s both.
  2. The design also shows an antenna that is divided into four sections, one more than the three sections of the antenna on today’s single-mode iPhone 4. This suggests that an entirely new type of network is being supported in the antenna. Again, it could mean LTE or GSM/UMTS/HSPA+, but again, I think it’s both.
Of course the stuff on Geek.com could be a hoax. But if it is a hoax, it’s one that must have taken a lot of work to perpetrate. I can’t see somebody designing and building a new metal dye and punching out just one set of parts just to make people think the new iPhone is dual mode and 4G. That’d be kind of crazy.
Also, the leaked video that appeared on Geek.com has now been taken down. When you try to play it, YouTube gives you a message saying “This video is no longer available due to a copyright claim by Apple Computer, Inc.” The fact that the video was indeed the property of Apple, and that the super-secretive company appears to have taken the trouble to take the video down may lend more credibility to the leaked images.

Verizon is LTE-happy

At any rate, the announcement of an LTE iPhone now would fit nicely with the pace at which Verizon is moving toward 4G and 4G devices. All of the premiere phones the company announced at CES are 4G LTE Android phones. Holding a big showy event in New York and announcing just a 3G Verizon iPhone would seem like a step back.

Apple Catches Up

The announcement of a 4G iPhone now is crucial for Apple. The iPhone was the King of All Smartphones in a 3G world. But we are clearly entering a 4G world now, and with more and better 4G phones being announced the iPhone looks more and more out of date. An “iPhone 4G” would catch them back up in a hurry.

Mathemagics adds to Mac App Store offerings



The makers of an iPhone app that teaches “math tricks” to aspiring mathletes have brought the program to desktop computers.


Mathemagics for Mac launched last week in the Mac App Store. Like itsiPhone predecessor from Blue Lightning Labs in Austin, Texas, the app claims to teach users 60 tricks for muliplying, dividing, and calculating square numbers “at lightning-fast speed.” The program is pitched at students preparing for the SAT and other standardized tests, as well as competitors in math contests.
Mathemagics lets users learn lessons at their own pace, learning its techniques through game-playing and with the aid of a stats tracker that monitors a “mathemagician’s” progress. Users can hide answers to problems until they’re ready to see if they’ve conjured the correct answer to the challenges posed by the program.
Mathemagics for Mac costs $5, and is compatible with computers running OS X 10.6 or later.

AT&T and Verizon iPhone plans compared




Many of you probably consider an Apple-Verizon deal the second coming of the iPhone. Perhaps you’ve suffered on AT&T since June 29, 2007, or maybe you’ve been biding your time with that dilapidated Motorola RAZR, waiting for the day the iPhone was to be liberated. Well, that day has come, so we did your Verizon iPhone homework for you to see how the carrier compares against AT&T, besides offering a potentially more reliable network.
I'll break down the carriers's voice, SMS, and data plans separately, since there's a lot to digest here. As the carriers offer so many voice plans in both individual and family flavors, I'm only covering the first three of each, in order to keep things simple. Besides, if you need more than 1500-2000 minutes, you're probably used to doing some extra homework anyway.

Voice plans

The carriers are neck and neck when it comes to their introductory voice plans for individuals, starting with 450 minutes at $40 per month and pacing each other up through the “unlimited” tier, which you can see below.
Family plans are where things get more interesting. Even though Verizon is the nation’s largest network by sheer subscriber numbers and it offers the same “call anyone else on our network for free” feature, the abundance of minutes on its voice plans here seem to assume that families are frequently going to call non-Verizon customers.
AT&T’s family plans start at 550 minutes for $60 per month, but Verizon’s begin with 700 minutes for $70, and head ever more upwards from there. Keep in mind, these plans include the minimum two lines to qualify as family plans, and both carriers allow up to five lines on a family account.

Text messaging plans

Note that Verizon and AT&T differ on SMS and data plans as well. While both let you add text messaging plans starting at $5, Verizon gives you 50 more messages for its base offering; past that, the companies differ in how fast they scale the number of messages in terms of what you pay, so the best deal will vary depending on just how much texting you do.
It's worth noting that SMS plans are optional, but who buys a smartphone these days and doesn’t use text messaging? It's not like you're actually trying to make phone calls, right?

Data plans

Data plans, on the other hand, are required for smartphones by both carriers, which is where Verizon's current plans may have an advantage over AT&T. Plus, unlike text messages or voice minutes, neither Verizon nor AT&T offer bundles for data; each phone has to have its own data plan. You may recall that AT&T dropped its unlimited smartphone data plan in June last year in favor of two tiered options, and Verizon introduced its own tiers in October, though it held onto an unlimited data option.
However, Verizon declined to say whether the existing smartphone data plans that it offers will also apply to the iPhone, saying only that it would announce data package pricing at a later date. So while the chart below shows the network’s current pricing, keep in mind that it’s very possible—if not likely—that iPhone data packages will differ.
It's also worth noting that Verizon announced its version of the iPhone will offer the carrier’s increasingly popular mobile hotspot feature, which lets smartphone users share their device’s 3G network connection with up to five devices via Wi-Fi. While this service usually costs an additional fee, Verizon also didn’t specify what it would charge iPhone users for the privilege. AT&T, for its part, currently allows tethering to one computer—not, for example, an iPad—via USB or Bluetooth, for which it charges an additional $20 per month.

Coverage

Verizon claims that it "covers approximately 290 million people," while AT&T boasts that it covers "97 percent of Americans." You can look at Verizon's interactive coverage map as well as AT&T's map, but since Verizon is the country's largest network and AT&T is a close second, it's going to come down to your personal experience. This is one place we can only do so much of the homework for you; you might need to do a little legwork to make sure Verizon works where you need it.
Verizon or AT&T may show your neighborhood or city blanketed, but it’s still possible you won't be able to get a signal in places that are important to you, like your basement or your office downtown. PCWorld's second 3G wireless performance test, performed around the U.S. last February, should be useful, especially if you live near any of the major metropolitan areas included in the review. But I encourage you to talk to some Verizon- or AT&T-toting friends in your area before jumping into a contract for the long haul. Or, alternatively, you could do your own personal wireless performance test by signing up for an iPhone and running around to all the places you want to check out within Verizonor AT&T’s 30-day return policies.

Closing thoughts

The minimum cost for both Verizon and AT&T with data and SMS plans is almost exactly the same, with a total individual plan price of $60 on both networks (again, this is assuming Verizon's current data plan offerings—that price is subject to change). Things get more interesting once you get into the family plans, as Verizon offers more minutes than AT&T, but charges $10 to $20 more, depending on the voice package. Still, if you've been suffering dropped calls on AT&T or simply prefer Verizon, that may be an insignificant price to pay for what the carrier boasts is a more reliable network.
And, of course, we'll have more plan details in the coming weeks, as Verizon still has to detail its data packages, including the charges for tethering and mobile hotspot.
Updated at 11:12am PT with a new chart to reflect that Verizon offers the same unlimited family text messaging plan for $30 that AT&T does.
