I have a custum alert tone that I want to use as my voicemail ringtone and yes, it's in .m4r format. Even though I've imported it into itunes, it won't show up when I go into settings and try to select it under tones for voicemail. Does it need to be in a different format in order to show up in the list of ringtones for voicemail?
If anyone wants the challenge of trying to solve the issue with the file themselves, I'm more than welcome to provide it to you. Just give me youre e-mail so I can send it to you to fool around with.
