Got a 1st Gen iPad, went to update it the other day on iTunes. Seemed like it all went well. Then I noticed my 3G signal was gone, so I tried to restore it. Since then, I can't get the thing to connect to my iTunes? I even deleted my current iTunes and redownloaded iTunes 10.2.2 again? I get "We're sorry we are unable to continue with your activation at this time" in the iTunes menu. I tried to power off, hold the home and plug in to force the restore process, but once it starts, it comes with the same message. The iPad screen is like a new screen with the USB picture and iTunes logo above it. It doesn't change. Anyone? Seems like the last update was the death of it?
