I cut a file from itunes in garageband to make it into a short file so i can send it through bluetooth to my cell phone to make it as my ringtone.... but it wont let me send it, a box comes up and says: "File Not Accepted: The target device claims it will not accept a file of the type you are trying to send" Is there a way to change the type of file it is so it can be compatible with my phone?? If so, how?? Is it possible?
