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.
