I'm still using version 1.0.2 on my iphone since i'm not in the US and upgrading it will cause blocking... and I have the new 7.5 version of itunes... I guess this combination will not work for customizing ringtones? I'm having the same trouble of: getting the ring on the "ringtones library" of itunes, but not recognized in the "ringtones tab" of the iphone area... and after trying to sync, the error message "... song cannot be played on this iphone" appears... Is there a solution? Or I just gonna have to update the phone? Thanks.
