Im trying to update my ipod because i want to download this app called restaurant mania and you need the latest update to get it but however when i click update it says this may take an hour or more to do.So when its like 2 hours over , the download bar on backing up is still less than half way.And i cant restore it because i heard it deletes all Progress on apps and deletes all your music.So can anyone help me ?? :S this would really help as it is really annoying me
