iMessage and FaceTime are crashing on iOS 6 beta 3

I have iOS 6 beta 3 on my iPod Touch 4th generation, and iMessage and FaceTime are crashing when I try to open them. Their sections in settings take a long time to load and are empty when they do load. Both work fine on my iPhone 4s, also on iOS 6 beta 3. Should I restore, or is there some other way to fix this?
