tap Change Passcode. Enter your passcode again, then enter and reenter your new
passcode.
If you forget your passcode, you must restore the iPod touch software. See “Updating
and Restoring iPod touch Software” on page 111.
Set how long before your passcode is required: Choose General > Passcode Lock and
enter your passcode. Tap Require Passcode, then select how long iPod touch can be
idle before you need to enter a passcode to unlock it.
Erase data after ten failed passcode attempts: Choose General > Passcode Lock,
enter your passcode, and tap Erase Data to turn it on.
After ten failed passcode attempts, your settings are reset to their defaults and all your
information and media on your iPod touch is removed by overwriting the data stored
on iPod touch.
Important: You can’t use iPod touch while data is being overwritten. This can take one
to four hours or more, depending on the storage capacity of your iPod touch.
