I tried restoring my ipod touch because itunes wont recognize it till i restore it. Soo when i try and restore it a message comes up that says "The ipod "ipod" could not be restored.The disk you are attempting to use if full". But the thing is, is that there is nothing on my ipod, and i dont have any warranty on it, and it has been jailbroken before. How do i fix this? My itunes is also updated.
