my friend and i traded ipods so now i have a 32gb jailbroken ipod touch, but when i wanted to sync it with my computer it wouldnt erase the apps already on the ipod or add new ones to my itunes library. i get a message saying that the apps have not been authorized on my computer.....but i cant authorize it on my friends computer because he does not have internet.. if you understand what i am saying i would really appreciate an answer.
