If you have a V Cast Music capable handset, the Music Essentials Kit allows you to synchronize music from your PC to your phone. It can synchronize both WMA and MP3 files although the MP3 files are converted in the process to WMA. Full length songs saved to your handset or memory card cannot be used as ringtones.
