jailbroken 2.1, 1g ipod touch 8gb, quickpwn 2.5. after about 2 months of being pwned, app store apps no longer work on my touch, tried deleting them all and then re-syncing, but no success. all jb apps work though. what do i do? any ideas? (happened once b4, except it was because swap tunes was swapped, i re swapped and it wnet back to normal. 1 week later (now) its messed up again. swap tunes is not on/working/w/e.) all help is appreciated.
