I bought this phone for the FM radio and MP3 playback even though I don't really like the swivel movement. The MP3 player works very well, although I really wish the phone had expandable memory. The radio works well and it is nice to have RDS (lets you know the title of the song and the station name). There is also a feature that you can use to control your PC via Bluetooth which is really cool, once I figured out how to use it. The manual doesn't explain this (or any other feature) very well. You must turn on HID profile in the Bluetooth setup menu in your PC's control panel (if you have Windows XP Service Pack 2). Then it couldn't be easier.To the reviewer who couldn't get the voice commands to work, you have to put your ear to the phone to hear the tone. It is a very quiet tone. I had to call Sony Ericsson to find this out.
