Neither my custom ringtones nor those purchased through iTunes are playing. I set to a song ringtone, called my iPhone to test . It does not play the song ringtone. Tried this with multiple ringtones, both custom & purchased. Only plays a standard ringtones. All custom & purchased ringtones are showing up in iTunes & on my iPhone. Synching is set to 'all ringtones''. Does anyone have a solution? Why won't my ringtones ring when I get a call & it defaults to a standard ringtone?
