updated version of itunes? I just downloaded ringtone maker app on my iphone 4 and i made ringtone on there but when i got on itunes and tried to follow the intructions it gave me on the ringtone maker app, it wouldn't work on my itunes. Im guessing it is bc i have the updated version of itunes. What is the best ringtone maker app that is free that will work on the updated version of itunes?
