you can use any type of music as a ringtone mp3 midi most phones play them all just cut em down to like 20secs so they dont take up much space...Or atleast i think they do, i sent an mp3 to my bro not so long ago and he uses it as a ringtone, i used a site that sends it to phones im not sure if they convert them to something else but it was free so i cant complane...
