Have the first generation iPad. I gave it to my son when I upgraded to the new iPad. It worked perfectly. I reset it, and my son set it up in his iTunes account. Now he has an error that says it has to be restored, when we tried to do that, it keeps getting errors saying it can't be restored, and random error numbers. What can be done at this point? I never had any problems like this before, any suggestions? Is it even worth fixing?
