The Sony Ericsson W880i has finally been formally announced. The device was previously dubbed Ai in rumors and was even featured in a few "spy shots" officially released by Sony Ericsson back in January. All the commotion was for good reason, at just 9.4mm thick the W880i is the thinnest phone [by a fair margin] Sony Ericsson has produced. As a Walkman branded handset, the W880i features a sophisticated music player and playback keys.
The smaller stature doesn't take away from features though, the W880i is well equipped:
Sony Ericsson expects to begin shipping to select markets the W880i in the current quarter. It will come in both silver/black and black/orange color schemes. There will also be a version without 3G called the W888c designed for the Chinese market. Because it lacks GSM 850 the W880i will not ship in the US.
