From MR Mobile comes news of the FlipSide MP3 Player beta for Windows Mobile devices. With FlipSide, you can flick your finger to browse through your albums. FlipSide will also download missing album art from the internet. Even better, a feature called "FlipSide Extras" offers Last.fm integration, which lets you look up artist info right from your mobile device. To sign up for the beta, you have to join the FlipSide Yahoo Group here: http://groups.yahoo.com/group/flipsidemobile. Then the OTA download will be sent to your phone for you to try.
