AT&T no longer works with your 2G phone
We hope you weren't planning to use your old-school iPhone or BlackBerry Pearl on AT&T's network for nostalgia's sake -- unfortunately, you're not going to get anywhere. As promised way back in 2012, the carrier has confirmed that it shut down 2G services on January 1st, 2017. If your phone only makes GSM calls and uses EDGE for data, you're stuck. The move won't hurt very many people (even basic phones have been using 3G and LTE for years), but it's hard not to shed a little tear for a technology that had been around for so long.

Bloomberg: Intel will supply modem chips for the next iPhone
Bloomberg is reporting that Intel will replace Qualcomm as the supplier of modem hardware for some models in the next generation of iPhones. The news service believes that the move is down to Apple's desire to "diversify its supplier" base for the best-selling devices. Intel will provide the wireless hardware for the GSM version of the device, compatible with AT&T and T-Mobile in the US as well as most worldwide carriers. Qualcomm, meanwhile, will still provide the gear that goes into the Verizon/Sprint model, as well as for other mobile networks that use the CDMA protocol.

Anyone in the world can buy an Ubuntu phone (but shouldn't)
If you were dismayed that Canonical's campaign to launch an Ubuntu-running smartphone crashed and burned, then today might be your lucky day. Spanish smartphone maker BQ has already been selling two Ubuntu devices to Europeans but, from today, it's opening that offer out to everyone in the world. The Aquarius E5 HD and E4.5 both run the much-feted Linux-based operating system and are available for just €199 ($218) and €169 ($185), respectively.

NSA can decode many GSM cellphone calls
The NSA may say that its phone surveillance efforts focus on metadata rather than the associated calls, but we now know that the agency can listen to many of those conversations whenever it wants. Documents leaked to the Washington Post by Edward Snowden confirm that the NSA can decode GSM-based cellphone calls without obtaining the encryption keys. The ability isn't surprising when GSM has known weaknesses, but the document suggests that the NSA (and potentially other US agencies) can easily process cellphone calls worldwide. Not surprisingly, the intelligence branch argues that such cracking is necessary -- folks on both sides of the law use encryption to hide information, after all. The NSA may not have such an easy time in the future, however. AT&T, T-Mobile Germany and other carriers worldwide are moving to tougher encryption methods for their GSM service, and 3G calls are typically more secure as a matter of course. These measures don't prevent eavesdropping, but they do complicate any attempts to snoop on cellular chats.

Unlocked and SIM-free iPhone 5s now available on Apple's site
You don't have to hold onto hope for that truly unlocked iPhone 5s any longer -- it's now available to buy on Apple's site. To be clear, this version of Apple's Touch ID-imbued flagship comes completely free of any carrier attachment, separating it from the unlocked T-Mobile variant that ships with a Magenta nano-SIM inside. The SIM-free GSM handset, which'll ship within one to two weeks from order, is available in the standard 16GB/32GB/64GB storage and color configurations, so pricing remains the same at $649/$749/$849, respectively. But you'll still need to hitch your data ride to AT&T or T-Mobile for that fancy phone to work in the US. So, the strings... they're still attached. There are just fewer of them now.

GSM Moto X dev edition brings unlocked bootloader on AT&T, T-Mobile for $650
A couple of days ago Motorola introduced the Developer Edition of its new Moto X for Verizon and as promised, it's followed up with one for GSM networks. If you're into running custom software, this is the one to buy if you want a Moto X on AT&T (it's also compatible with T-Mobile's LTE) thanks to its unlocked bootloader. Otherwise it's the same as the earlier model, with "Developer Edition" branding on the back and 32GB of storage inside. You'll have to live without Moto Maker customizations, but picking this one out of the sudden rush of Developer Edition models available may be the toughest part.

MetroPCS to start using T-Mobile's network and GSM handsets June 12th
And so it begins. With T-Mobile recently closing the deal to acquire MetroPCS, it was only a matter of time before we'd see more commingling. PhoneArena's uncovered yesterday that MetroPCS is about start using T-Mobile's network and GSM handsets. Two phones which are currently available on T-Mobile -- the recently launched Samsung Galaxy Exhibit (a Galaxy S III mini clone) and the LG Optimus L9 -- are making their way to MetroPCS, complete with GSM / EDGE and AWS-capable UMTS / HSPA+ radios (no LTE). Pricing for these devices is still unknown, but the company's expected to begin selling plans on T-Mobile's network as soon a June 12th. In addition, a service called BYOP (Bring Your Own Phone) will allow customers to bring their own GSM handsets to MetroPCS (excluding BlackBerry models). It's unclear if eligible devices have to be unlocked and / or T-Mobile branded but we'll find out soon enough. So there you have it -- the start of a perfect honeymoon.

ASUS K005 tablet hits the FCC, Snapdragon S4 Pro hints at top-tier performance
Although ASUS recently delivered the $150 7-inch MeMo Pad and PadFone Infinity combo device, it's been a while since a premium Android tablet graced the lineup. A recent FCC filing from the company, however, reveals an unannounced K005 model equipped with the venerable Snapdragon S4 Pro (APQ8064) SoC clocked at 1.7GHz. Further details are light, but G4Games notes that it reveals AT&T-compatible GSM, CDMA and LTE connectivity and the model number suggests a 10-inch frame. Check out the FCC filing for yourself below and rest assured that we'll fill you in when we hear more.

Twenty years after the birth of SMS, its creator consents to a text-only interview
Finnish engineer Matti Makkonen famously dreamed up the idea for the SMS (Short Message Service) in a Copenhagen pizza shop in 1984, and the first message ("Happy Christmas") was sent to a Vodafone UK cellphone from a PC on December 3, 1992. Since then, an estimated 8 trillion texts have been sent, and now the normally recalcitrant pioneer has given the BBC a rare interview (appropriately via text message), where he discussed "txtspk,' keypads vs. touchscreens, and the next big tech development. While described as the father of SMS, Makkonen is still reluctant to take sole credit, saying it was "the result of a joint effort to collect ideas and write a specification." On top of that, he never felt the idea was patentable and therefore never saw a penny from the invention, despite its present day pervasiveness. As for textspeak, the engineer refrains from creating abbreviated messages himself, saying "my passion is to write correct language (Finnish), using all 160 characters." He's happy to do this using a modern touchscreen phone, although he couldn't resist using the interview to pay a charmingly backhanded compliment, saying they're "slow enough (that I can) think and sometimes even edit what I write."

Android 4.2 reaches some Galaxy Nexus phones early, grab the GSM version here (update: Nexus 7, too)
As Google Play groans under the clicks of early shoppers, Google's apparently got its software sorted too. A new Android 4.2 file for the Galaxy Nexus over at XDA-Developers matches reports we've had from users who have already been gifted the latest version of Jelly Bean over-the-air. Now, this is the 'takju' version, meaning it's meant for GSM devices ordered directly from Google, although the phone meddlers at XDA-Developers already have all the details needed to make the switch to this specific iteration. Sure you've got the right GSM Galaxy Nexus? Then, once you've read all the instructions and warnings from those aforementioned developers, you can pick up the download at the source below. Update: We've added a link to download the Android 4.2 file for the Nexus 7 also. Enjoy!

Bring the noise! Sony confirms HD Voice support for Xperia T
In the fast moving world of smartphones, giant HD displays just aren't enough anymore. The new hot commodity in the land of mobile is "HD Voice." Sure, the technology isn't exactly brand new, but using it over post-3G high speed networks is. The selling point here is high quality noise cancellation, which allows a phone's user to be heard clearly in the noisiest of environments. The latest device to hop on the bandwagon is Sony's Xperia T. When describing this feature, the herculean consumer electronics maker got downright emotional saying, "you feel closer to the person you are talking to." While we're not too sure about that, HD Voice did impress during our ears-on session. The major caveat here is that this feature requires that both parties have HD Voice capable handsets. So, until this concept becomes more mainstream, Xperia T owners' phone calls are likely to be close, but no cigar.

Next-gen Casio G'zOne makes it to the FCC, reveals LTE and NFC support
The last Casio G'zOne handheld to come our way was the Commando, a military-grade device that marked the company's first foray into Android smartphones. Now it seems there's another one in the works, at least if a recent FCC filing is any indication. The Casio C811 looks to be a successor to the aforementioned Commando, with its G'zOne branding and features like WiFi and GSM world phone capabilities. Notably, the FCC document reveals the phone has Verizon-flavored LTE plus NFC support, both of which lead us to believe it'll likely be a mid- to high-end handset. Not much else is divulged from perusing the filing, but we're sure that whatever the C811 turns out to be, it'll be just as tough and durable as the rest of Casio's G'zOne offerings.

Nokia Lumia 820, 920 for AT&T swing through the FCC
Hopefully AT&T subscribers weren't spooked when the Nokia Lumia 920 first passed through the FCC in only its non-US guise, and its lower-end 820 cousin only as the (currently unofficial) Verizon-ready Lumia 822. The two Windows Phone 8 flagships have had follow-up approvals in GSM versions that are unmistakably destined for AT&T and Canadian carriers. Never mind the slightly distracting RM-820 model number on the Lumia 920; it reveals the 920's distinctive curved design, 700MHz LTE in AT&T's range and AWS-based LTE for both AT&T as well as its Canadian neighbor. The Lumia 820 is equally identifiable as the RM-824, even if it limits the LTE access to AT&T's network. We haven't seen any shocking revelations from either device, although we weren't expecting any from phones that hew so closely to the original templates. The filings mostly set expectations for Microsoft's October 29th event -- now that the likely stars of the show are cleared to make their appearances, the companies involved should breathe more easily.

Samsung P500 and i915 tablets for Sprint and Verizon, Galaxy Note II for Sprint reach the FCC (update: Note II for US Cellular as well)
When it rains, it pours. As if to clear the decks, Samsung has passed three devices through the FCC's scrutiny at the same time. Two, the SPH-P500 and SCH-i915, are LTE-equipped tablets respectively headed to Sprint and Verizon with a dash of mystery; their label images imply a pair of Galaxy Tab 2 variants, but both have previously been spotted in as yet unverified benchmarks that allude to much faster Snapdragon S4 processors instead of the Tab 2's TI chips. The SPH-L900's dimensions and dual-mode support make for a safer bet, pointing to what's likely the Galaxy Note II for Sprint. We're less concerned with the hardware details so much as when everything ships -- although we may get a clearer picture of the Sprint Galaxy Note II's fate around October 24th, the tablets aren't linked to any kind of public schedule, official or otherwise. Update: Not long after Sprint's Galaxy Note sequel arrived in the FCC, US Cellular's flavor -- the SCH-R950 -- also made it through the federal approval process.

Sony Xperia tipo and tipo dual reach the US in unlocked form, give Americans a taste of dual SIMs
Few of us who live outside of Asia or Eastern Europe know the potential convenience of a dual SIM phone. Own one and you can globetrot, or else keep separate home and work lines without the bulk of an extra device in the pocket. Sony is gambling that enough Americans have that multi-line desire by selling the Xperia tipo dual and its regular, single-SIM counterpart in the US as unlocked GSM models. Neither of the Android 4.0 phones is what we'd call a powerhouse with the same 3.5-inch screen, 3.2-megapixel camera and 800MHz Snapdragon inside, but both can latch on to HSPA 3G on AT&T, refarmed T-Mobile coverage and 2100MHz carriers abroad, even if the single-SIM tipo curiously has 900MHz 3G support that the tipo dual lacks. It's undoubtedly price that Sony is counting on more than anything: at respective contract-free prices of $180 and $190 for the tipo and tipo dual, the pair of Xperias may be sold most often as travel-only phones for the jet set.

Qualcomm reveals quad-core Snapdragon S4 Play processors, ramps up entry smartphone speeds
Don't think Qualcomm is limiting its quad-core processors to superstar phones. The Snapdragon S4 Play line is growing to include the MSM8225Q and MSM8625Q, parallels to the existing two Play chips that bring four cores to entry-level devices. Besides the speed improvements that you'd expect from all that extra parallelism, the Q variants support the extra bandwidth of low-power DDR2 (LPDDR2) memory and can handle both 720p displays and movie-making. Neither is quite an all-encompassing solution, although the two will cover the bases for much of the starter demographic: while local wireless such as Bluetooth, FM radio and WiFi have to remain separate from the main processor, the two newcomers manage to pack either single-mode UMTS 3G (in the 8225Q) or dual-mode CDMA and UMTS (in the 8625Q) for their cellular fix. Along with the already promised, China-focused S4 Plus MSM8930, test samples of the faster S4 Play editions will be ready before the end of the year, with shipping phones on the way in early 2013 -- just in time to go head-to-head with a similar push by MediaTek to make quad-core the norm for a much larger slice of the population.

Verizon has no plans to re-lock iPhone 5's GSM and 3G sides
When we learned that Verizon wouldn't lock the GSM-related components of the iPhone 5, we were waiting for a "gotcha" moment. Surely the carrier would clamp down and steer us back towards its more expensive roaming plans, right? Not according to Verizon spokeswoman Brenda Raney: she says there's no plans to lock Apple's handset at a later point. In other words, you should be free to use a Verizon-locked iPhone 5 on any compatible GSM and HSPA+ networks for as long as you'd like, including with AT&T and Canadian carriers. Of course, this still brings the caveats of having to both buy a Verizon model, either at full price or with a contract attached, and track down a nano-SIM for the carrier of choice. It could nonetheless settle the question of what carrier to pick if you regularly need a passport when you travel -- especially knowing that neither AT&T nor Sprint will be quite so open-minded.

Verizon's iPhone 5 ships unlocked, likely thanks to FCC
When the iPhone 5 arrived on doorsteps last week, some Verizon customers were surprised to discover the handset was unlocked on international and US-friendly bands, as iDownloadBlog pointed out. This means customers can sign up for Verizon, stick an AT&T nano SIM in the phone (or chop up a conventional chip) and it'll work out of the box. Granted, it won't connect on the GSM carrier's LTE service, but it will work fine on the older network. This also means VZW customers can travel overseas and not have to worry about asking Verizon to unlock the phone before they leave. (Traditionally VZW will unlock a phone for customers in good standing after 60 days on contract; unlocking does not absolve you of your two-year contract obligation.) Earlier models of the iPhone could be unlocked for international use, but not for domestic use on carriers like AT&T or T-Mobile. It's unusual for a carrier to sell a phone that can be easily used on another carrier and polymath Java developer / photographer James Duncan Davidson did some digging to find out why Verizon is now offering the iPhone in an unlocked state. He tracked down, via Howard Forums, the notion that federal regulations apparently require Verizon (using the 700 Mhz Upper C block of spectrum) to sell the LTE iPhone unlocked. The forum thread points to Title 47, Part 27, Subpart B, Section 27.16 of the Code of Federal Regulations which says: (e) Handset locking prohibited. No licensee may disable features on handsets it provides to customers, to the extent such features are compliant with the licensee's standards pursuant to paragraph (b)of this section, nor configure handsets it provides to prohibit use of such handsets on other providers' networks. This wording appears to prohibit Verizon -- the auction winner for the relevant chunk of radio spectrum, which was used for analog UHF television channels until February of 2009 -- from selling the LTE iPhone carrier-locked. There are still some unanswered questions; this doesn't explain why Verizon sells its Android LTE phones locked to its network, for instance. The implications of these spectrum rules were discussed back at the time of the auction for the spectrum block. This Susan Crawford post, from 2008, notes the rules but also points out that Verizon would be able to claim exceptions for "reasonable network management and protection" and regulatory compliance requirements. Regardless of the reason why the Verizon iPhone is unlocked, it's an important feature for people to consider when they are shopping for an iPhone, especially if you travel or see yourself switching carriers in the near future. Of course, customers are still under contract with Verizon if they buy the iPhone at a subsidized price, but the convenience of having an unlocked phone may be worth the cost of a two-year customer agreement.

Verizon iPhone 5 is unlocked, able to accept GSM SIMs right away
Great news for those waiting anxiously at the door for their UPS / FedEx delivery... well, for those awaiting a Verizon iPhone 5, anyway. We've already broken down the differences between the trifecta of iPhone 5 models, and it seems that the one VZW is hawking is a real gem for travelers. Aside from handling Verizon's LTE waves just fine, the nano-SIM slot will also accept cards from any other GSM carrier worldwide. In other words, AT&T nano-SIMs will get you onto its HSPA+ network, and T-Mobile nano-SIMs will play nice as well. If you're heading overseas, you can pick up a local nano-SIM on arrival and plug it straight in -- no unlocking code necessary. To confirm, this even applies to Verizon iPhone 5 units that were purchased under contract. You can hit the video after the break for proof, but heed one word of advice: wait until you find a legitimate nano-SIM to throw in there. It looks as if the cut-and-stuff approach leaves a bit to be desired.

No, Virginia, you can't have a universal LTE iPhone 5
There might be a Santa Claus, but regarding the mythical animal known as the universal iPhone: there is none. As noted on Apple's spec page for the iPhone 5, the company will be shipping independent GSM and CDMA models of the new phone to match the LTE frequency bands of carriers worldwide. The iPhone 4S, in contrast, supported all its compatible wireless standards in one device. There's likely to be some confusion around the iPhone 5 model numbering, since there are three actual hardware configurations but only two model numbers: A1428 and A1429. The singular A1428 model is the AT&T and Canadian GSM phone, with support for UMTS/HSPA+/DC-HSDPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz) and LTE on bands 4 and 17. Since this phone lacks any CDMA support, it cannot be used with Verizon or Sprint networks in the USA; it could theoretically be unlocked for 3G service via T-Mobile's seven-year roaming agreement with AT&T. The A1429 phone has a split personality, with both CDMA and GSM units carrying the same designation; the GSM model, however, does not appear to be intended for sale in the US. It supports LTE in the Far East (Singapore, Hong Kong, South Korea and Japan), Germany, Australia and the UK on bands 1, 3, and 5. The CDMA version of the A1429 works with LTE on Verizon and Sprint's networks, plus the KDDI network in Japan -- LTE bands 1, 3, 5, 13, and 25. The CDMA phone also supports the GSM bands, so it should work as a "worldphone" for international travel even if it doesn't include LTE data support outside the US and Canada. The upshot of all this model madness: You will not be able to interoperate different iPhone 5 models on different networks in the US. Switching carriers (assuming you managed to get an unlocked device) would be limited to intra-standard swaps, and an AT&T iPhone 5 will never work on Verizon / Sprint, end of story.
