The new mid-level Walkman phone from Sony Ericsson is available from AT and T and unlocked from SonyStyle (we review both versions). This quad band GSM phone has EDGE for data and is small, really small. The slider design is sturdy and the curvy profile is attractive. It's available in white, black and gray and it has the usual full-featured Walkman phone music player, excellent audio quality, Music ID and an FM radio. The 2 megapixel camera takes quite good shots and there's a Memory Stick Micro slot to save photos and store music.
