iOS 4: Updating your device to iOS 5 or later

  2. Update your device to the latest version of iOS software.
  3. Restore your device from your most recent backup.
  4. Restart your device.
  5. Sync back media content from your iTunes Library to your device2.

You can restore this content by syncing with the Mac or PC with which you normally sync.
  3. Movie rentals purchased directly from your device will not get transferred to your computer when you sync and transfer your purchases.
