A lot of people wrote T-Mobile off when its big merger with AT&T fell through last year. The pink carrier had no iPhone, no 4G. But with yesterday's announcement of the company's official LTE rollout, it may have just put itself in a position to offer something no one else can.

While the One X may be HTC's beast of a flagship device, the One S is not far behind. It's packing a new Snapdragon S4 processor into one of the most solidly built phones I've ever put my paws on.

Nokia Siemens is going to demo HSPA+ Multiflow—a new cell tech that lets phones talk to two cell towers at once—at Mobile World Congress. It's the first time that the tech, which can apparently double data speeds, will be shown working on stuff you might actually be able to buy.

As of Sunday, AT&T is going to have some new data plans on offer. It's not some super-sweet double-data-deal, but it doesn't suck either. Basically, you can add a gig of data to your plan for five bucks.

Oh Snap. HP may be launching a new glossy, white webOS tablet in August. This new model comes hot on the heels of the original TouchPad which launched last week.

The iPhone 4 takes fantastic pictures, for a phone. With the myTouch 4G Slide, HTC's promising the first phone since the iPhone that takes better pictures and doesn't suck at, well, everything else.

RIM's first tablet has been slated for a March release, but if you've been strongly considering buying one, you may want to hold off until the "second half of 2011," which is when RIM will release LTE and HSPA+ versions—joining their two other models.

AT&T's got new data plans to go with the wireless hotspot feature debuting in its first 4G Android phones—which they're "working with Apple to bring it to iPhone"—and they actually screw you less than before.

Samsung's just made the Galaxy S 4G official, though they're offering up curiously few details. It's coming to T-Mobile's HSPA+ network—Samsung's first to support the full 21Mbps—it'll have a Super AMOLED display and it'll run Android 2.2. [Samsung]

It's conventional wisdom now that iPhone exclusivity is the best and worst thing that ever happened to AT&T. A rocket that sent them into space—and directly into the sun. Will the same thing happen to Verizon?

"Holy shit." It's not what usually comes to mind when I touch a new phone. But Samsung's Infuse 4G is spectacular. Ridiculously good 4.5-inch screen. 1.2GHz processor. 4G on AT&T. Why, exactly, wasn't this the new Nexus phone?

AT&T is going call their HSPA+ (normally considered fast 3G), 4G, like T-Mobile. They're also going to start deploying their LTE network (Verizon's type of 4G) starting this summer. For an explanation between the two, see here.

T-Mobile's not quite ready to put it's full support behind the 4G mobile broadband infrastructure. Instead, they want to take the current 3G HSPA standard they're using, and make it as fast as 4G, reaching speeds of 650Mbps.

Verizon's pretty-damn-fast LTE network is launching in four days. They're calling it 4G. Sprint calls its WiMax network 4G. T-Mobile calls its network 4G too. Confused? Check out our primers on WiMax and LTE and what 4G really means. [Gizmodo]

The next T-Mobile myTouch, which looks to be a fine phone, as T-Mobile's first video-chatting Android phone, is being re-branded as the myTouch 4G. But it's not really 4G. It's pretty lame of them to call it that.

The official sequel to the first Googlephone, the T-Mobile G2 is a long time coming. In a market where carriers molest the open OS anew every time a new handset drops, this is the Android phone for the Android nerd.

They can't call it 4G (as explained here), but their HSPA+ is almost as fast. Now, even more cities have been added to the map—including San Francisco, San Jose, Sacramento and Phoenix. See the full list below.

The newest myTouch iteration goes balls out with video: Video chat over Wi-Fi and T-Mobile's HSPA+ network with a front-facing camera and 720p video recording with the rear camera—shared wirelessly with any DLNA-compatible screen.
