hey, maybe it's cause i'm new to the itunes software but after reading up on how to make custom ringtones i was able to create a few. later on when i went on to make more i must have messed up and even the new ones are listed on the ringtones part in itunes they aren't on my iphone when i sync. i was hoping someone could tell me how to CLEAR THE RINGTONES completely of the custom ones i made so i could start over.

PLEASE HELP!!!!
