This has probably been asked before... but I'll do it again anyway...

If I want to use an mp3 from my computer as a ringtone on my v400, can i send to my phone via MMS... or is the only way via the data cable. I've sent midi files and they work, however, i modified an mp3 to 64kps (the same as the ones i pay for) and sent them... my phone recognizes it's a music file but when I press Play, it says "System Error"
