When I updated my iPod software to 1.1.2 I received this error as soon as it was done and my iPod didn't update. The whole update was complete but it didnt install. when I clicked the update button again it tried to download the update again! I cant download it again as my monthly data cap has almost been reached. Where does the update download to so that I can install it some other way. Ok, I found it in HDD>Users>User>Library>iTunes>iPod Software Updates. How do I use it now?
