an error occures it says just "preparing iPod for restore" and after minute or two it says "The iPod "iPod" could not be restored. An unknown error occurred (1601) or (1604) or a million other error codes. I think this is because Apple make upgrades incompatible with older ipods. It has happened on 3.1.1 and again with 3.1.2 I am never upgrading my old ipod again!!!!!!!!!!!!!! the ONLY fix after this Apple logic bomb is to open your ipod and disconnect the mother board to force an internel reset. It sucks the big one, thanks Apple......... Not!
