AT&T has officially launched the Sony Ericsson Z750a clamshell cellphone in grey, purple, and pink today. The Z750a is Sony Ericsson's first handset to support dual-band WCDMA (850/1900MHz) on AT&T's high-speed 3G network. This clamshell features a smooth mirror finish with a hidden OLED display on the outside. Inside there is a 2.2" QVGA display capable of 262k colors.

The Sony Ericsson Z750a features a 2 megapixel camera with video capture, and a memory stick micro (M2) card slot allows for plenty of storage expansion. Bluetooth 2.0 with A2DP support for stereo headsets is also on board, in addition to an FM radio tuner and speakerphone. The Z750a's web browser supports full HTML web pages, which should make it easy to really enjoy that HSDPA data connection, as well.
