When the press release on the Sony Ericsson Z750a crossed the wire this morning, we thought that model number looked familiar. That’s because it was announced a year ago at CTIA 2007. Nevertheless, phone fashionistas will probably find a lot to like about this 3G clamshell, including its mirrored casing and hidden OLED display (which discretely displays caller ID info on the lid). It’s also available in three color choices: Mysterious Purple, Phantom Grey and Rose Pink. Under the Z750a’s hipper-than-thou exterior lies a blazing 3G HSDPA data connection, a 2-MP camera, a media player (with up to 8GB of capacity via a Memory Stick Micro card), and 3D gaming capabilities.
