We're still smarting from the apparent cancelation of the fabulously powerful K850 from AT&T's 2008 lineup, but as consolation prizes go, the Z750a ain't bad. That being said, it's solidly seated in the midrange, which seems like an unusual place for Sony Ericsson's very first carrier-launched 3G handset for the US to be; the 2 megapixel camera isn't going to "wow" anyone, and the choice of colorful, ultra-gloss shells definitely limits the phone's appeal to a certain demographic. On the bright side, the music player has an XMB appeal to it -- users of other recent Sony Ericssons will feel right at home with the app -- and it's one of the better built-in players currently available on any handset. The Memory Stick Micro slot makes that player just a little trickier to use for anyone that isn't already using Sony Ericsson kit, but c'est la vie, we suppose. Check out some shots in our handy dandy gallery here.

It's not a surprise, but it's still overwhelmingly refreshing to see Sony Ericsson finally (and we do mean finally) bringing some 3G action onto AT&T. The "a" variant of the glossy, colorful Z750 clamshell will be hitting AT&T in an official capacity come early April, featuring an OLED external display cleverly concealed by the phone's translucent shell, a 2 megapixel camera and media player both backed up with Memory Stick Micro M2 expansion, stereo Bluetooth, and of course, that lovely HSDPA 850 / 1900 that's eluded Sony Ericsson's AT&T offerings for far, far too long. Look for it to go out the door for $49.99 after a $100 rebate.

We've just received a fresh round of release dates on AT&T, and if we had to pick a single word to describe the theme here, it'd be "colors." Shades upon shades of phones -- both new and old -- will see a release on AT&T in the next couple of months, starting with the Sony Ericsson Z750a, the first 3G Sony Ericsson to be released by a carrier in the States (but not in North America -- that honor belongs to Rogers); it'll hit in your choice of gray, pink, or purple in early April. The now-ancient UTStarcom 5700 finally sees release toward the end of April more than a year after we first saw it in the FCC's business, giving a lower-end choice to the Windows Mobile faithful. Finally, May should bring about the LG CU720 Shine in black, following its initial offerings of silver and red.

Oh, and it looks like the Motorola Z9 and the black Centro should be widely available pretty much any minute now -- stay tuned. Strangely missing from the list is the Vu, though that doesn't necessarily mean it won't be released by the end of May, it merely means that AT&T's not sure yet. Surprise, surprise.

It looks like Sony Ericsson may be taking a slightly more high-road approach to its first 3G handsets for North America than Nokia did with the N95, pairing up with AT&T all official-like for the Z750a and K850a. This inventory sheet, apparently off of an AT&T system, indicates as much -- and yes, we realize it's totally Photoshoppable, but the Z750 and K850 both seem like obvious additions for the carrier, don't they? Sony Ericsson could try to sell the phones directly through SonyStyle as it does with other models, but you figure that if they're going to put the effort into finally adding North American 3G, they're going to try to go big by launching it in AT&T stores. With a 5 megapixel camera on the K850, who's complaining?
