I'm having issues updating to 1.1.2 after Jailbreaking 1.1.2. I keep getting Error 1602 after about 30 seconds of it 'Preparing to update iPod'. I have installed OkToPrep and the BSD Subsystem (as per guides) then attempted to update (not restore) to 1.1.2 and it fails. Any ideas? Running iTunes 7.5 on a PC.
