Hey guys, I need some help... when I hit shift and click retore at the same time and choose the 4.0 restore firmware it keeps telling me that it is not compatible! Why? Oh and to let yall know my ipod is jailbroken running 3.1.3 if it helps. And the reason why i'm not just hitting restore and update itself is because our internet is so slow that it takes a couple of hours to download so i downloaded it from a different pc....
