everything was working fine since the 12th, and then all of a sudden this evening my music app stopped opening. i get either an empty window or just a black screen. sometimes it freezes the whole phone, sometimes i can just home-screen it out. the videos app seems to work. i mean, it opens at least but i don't have any videos to watch. tried a hard reset (several, actually). haven't resorted to re-installing the OS yet; hoping that since it HAS been working, there is a way to make it work again. i know lots of people are having issues with iOS 5 and the music app specifically, but anyone else not able to open it at all? i'm tired and i need my podcasts thanks for your help.
