It must be Sony Ericsson month-- two new phones for ATT and an unlocked high end Walkman phone. The Sony Ericsson W518a is a mid-level Walkman phone disguised as a super-thin flip. It's attractive, well made and not too slippery. Better still, it has very good music playback quality and runs the usual likable XMB media interface with Walkman 3.0 software. The budget-priced flip has a GPS with AT&T Navigator, 3G, a full HTML web browser, Bluetooth with stereo support and a 3.2 megapixel camera. Not too shabby.
