I just got an email to let me know that FlipSide MP3 Player has been updated for OS 5.0. This new version takes full advantage of the audio control playback features in the latest OS. You can now play, pause, next track and previous track with the audio playback keys on 5.0 devices. The coolest update is that since FlipSide supports both Bluetooth AVRCP and A2DP, you can now control FlipSide through a car stereo, speakerphone or stereo headset. FlipSide plays MP3, ACC, WMA and M4A files, download cover art, allows you to create playlists, auto-pause on incoming calls and more. It sells for $9.95 in the CrackBerry App Store and a free trial is available.
