ok so i recently got a 32gb refurbished ipod touch 3rd gen ffom the apple store. i set it up normally and it worked ok, strangely though, it would randomly reboot. i googled this and learned that i had to restore my ipod to factory settings. when i did, it gave me an "unknown error 9" now, when i try to restore it, i hear the usb inserted sound constantly and it says that it cant be restored. can it be restored or should i just get it exchanged?
