Question: Error code 21 when restoring?
I have a 6 month old iPod touch 4th gen. When I try to restore it using iTunes 10.5.3 on a brand new Mac Book Air 13inch, it comes up with an error code of 21, and leves my iPod in recovery mode. I have been able to get it out. I have tried to Reset it on the device it self, but the little 'spinner' that comes up when you turn off comes up and stays there and does nothing.
iPod touch, iOS 5.0.1, And using a mac book mid 2011
