If you let the upgrade fully implement and complete it should have restored from the backup it created prior to the upgrade. If you haven't backed up your iPad (just allowed it to sync) you should be able to restore from backup.Any help or suggestions would be appreciated. I updated to OS5 on iPad 1. To be safe, I read the tips and trouble shooting pages first. As I understood it:
BUT when I restarted EVERYTHING is gone, books, apps, accounts etc.
