Ok, as most of you, I had installer.app and also itoner for my ringtones. Well after the update I went to see if my ringtones were still there and they weren't (no suprise) but I had a few assigned as custom tones for Jamie, Renee, Abe, and etc. and Jamie just called me today and it still played that custom song! So they aren't visible but they still work for those people. Thought that was kinda weird.
