Hiya guys, I recently got my new iPod touch (64gb) and as soon as I upgraded to the latest firmware, my apps no longer work. As soon as I open one, it closes in a second. It's not jailbroken, I tried deleting and reinstalling but didn't work either. I don't know what to do, and I'd really like to avoid returning it. Anyway I'd really appreciate some help, thanks in advance.
