As a lot of people had last night the Apple servers were very busy with iPads and iPhones upgrading to iOS5... So I waited until this morning to upgrade. iPhone 4 no issues at all and now using iOS5 iPad (version 1) backed up but not is coming up with the following error: The iPad "iPad" could not be restored. An unknown error occurred (1) Typically error 1 isn't on the list and I can only find a handful of similar comments with no luck in fixing this. The error appears when trying to restore the firmware and I have tried rebooting my mbp and iPad multiple times. I have even resorted to installing iTunes on my Windows 7 PC where I also get the same error. Anyone had any luck in getting past this?
