Hi all, I've had this problem for a while but previously had simply worked around it. I've got a number of ringtones I made with an iPhone-ringtone-creator app. If I rename them to .m4r and sync them up through iTunes, I see no custom ringtones on the phone (when checking on the phone- iTunes itself shows that the phone has these ringtones on them). If I use the iPhone ringtone app to upload them, they worked fine. But then I couldn't sync from iTunes, or I'd lose everything. Well, that app was a Windows app, and I've replaced my Windows desktop now with a new OS X machine...and the new machine has the same issue. So I finally decided to buckle down and ask for help Anyone seen this before?
