I was on the phone with Apple (I have Apple Care Plus) for over two hours. We tried everything, and it will not restore. I keep getting "error 21". He even took over my computer and uninstalled all kinds of things that he thought might be causing it, and nothing worked. Now, I have to drive over two hours to the closest apple store, to get my new phone, because I didn't want to be without a phone for that long. At least it is free, I just wish the gas for the trip was lol. Have any of you ever heard of this problem before?
