This may have been posted somewhere else but, I was unable to find it. I recently upgraded to an I-Phone 5. I routinely assign specific downloaded tones to some contacts for text messages. I have noticed that some work and some do not. I have reloaded the tones, as well as deleting/re-entering the contacts affected. Still no luck. I have compared the settings side-by-side with the 4S I just upgraded from and they're identical. Any suggestions? Thanks in advance!
