Does anyone know a good website from which i could compose a ringtone using the ringtone composer on the 7650

Better yet, why don't you do a search for midi sites then upload them onto the phone. The quality is a lot better then any you could compose on the phone itself. The composer only allows for mono ringtones not polyphonic.

You can have the actual song as a ringtone.

You need to grab 15, 20 seconds of the song.. in MP3 format. Then load it into Winamp and export it as a WAV file.. Upload that file to your phone.. and it plays it

If you can grab X amount of seconds from an MP3 file and save it, i can talk you through the rest.
