I have a 32GB 1G iPod Touch and I'd like to downgrade it to 2.2.1, as I think OS3 is having issues operating with my Ford's Sync system.
I managed to downgrade to 3.0 by simply putting the iPod into DFU mode and loading up a OS3 firmware file I got from the 'net, but the 2.2.1 firmware causes either a Error 1600 or Error 20, depending on whether I restore it in DFU mode or not.
Any suggestions?
