Sony Ericsson W580i White Phone.

The W580i Walkman phone offers a full-function digital audio player that's compatible with MP3 and AAC files. The front of this slider phone includes dedicated music control buttons, and it includes Sony Ericsson's innovative "shake to shuffle" feature.

With Shake control activated, press and hold the Walkman key and flick your wrist. A vibration lets you know that the track has been changed--a new song from your current playlist is randomly selected and automatically played.

Not only that, with AT&T's Mobile Music service, you can access your Napster subscription service for music downloads to keep you booming out the tunes for up to 20 hours.
