I've just got an iphone 3g from my brother, and it's only in iOS 3.0... i tried to update it directly using iTunes to 4.2 but after finished downloading, it keeps hanging when it's trying to back up the file from the iphone... Can anyone help me??? Is it necessary to restore the iphone back to the factory condition?? after i restore it, will it change the settings back to locked (i mean it's an unlocked iphone 3g so will it be back to it's original state where it can only use the SIM card that comes with it)???
