If something isn’t working right, try restarting i Pod touch, force quitting an app, or resetting i Pod touch.
Restart i Pod touch: Press and hold the On/Off Sleep/Wake button until the red slider appears.
Force quit an app: Press and hold the On/Off Sleep/Wake button for a few seconds until a red slider appears, then press and hold the Home button until the app quits.
You can also force an app to quit by removing it from the recents list.
i Tunes won’t automatically back up an i Pod touch that isn’t configured to sync with that computer.
You can also sync manually by clicking Sync in i Tunes.
The tool is currently in beta and works only on i OS 8.3 and i OS 8.4.
