My original iPad has been constantly crashing. I'm using iOS 5.0. I was at the Apple Store recently on another matter and the Genius there said I should re-install the OS from scratch but *not* do a restore. She said I should do everything manually, including re-installing all apps by hand. And only then should I restore data from the cloud. Just want to confirm that I understood her correctly. Is this the correct way to proceed? If so, what's the outline of steps to take?
