The first time I encountered this problem was at school. I was listening to music on my itouch, then all of a sudden the apps were acting strange. I would tap one, it would open for like 2 seconds, then close immediately. Then every single app did it. I performed a system restore hoping that would fix the problem, it did...but not until today. Just when I synced my itouch to itunes to add some songs the apps starting acting like that again, now I can't open a single one. I really don't want to restore my itouch again because I've added so much songs and apps that I don't want to lose and I have a feeling restoring it won't help again. I hope anyone out there knows of this problem or knows how to fix it

Thanks!

iOS is 4.2.1
