Hi. I just installed iOs 5 for the first time via beta 4. Yeah, I just hadn't gotten around to it. However, after I updated it, the only thing that remained on the iPod after the restore was my photos. Music and apps were removed. I tried to sync them with my iTunes library but the sync button is grayed out in the music section of the iPhone window. When I try to apply and sync apps it hesitates then does nothing. Someone please help. This is quite annoying.
