Updating and Restoring iPod touch Software
You can use iTunes to update or reinstall iPod touch software, restore default settings,
and delete all data on iPod touch.
 If you update, the iPod touch software is updated but your downloaded applications,
settings, and songs are not affected.
 If you restore, the latest version of iPod touch software is reinstalled, default settings
are restored, and data stored on iPod touch is deleted, including downloaded
applications, songs, videos, contacts, photos, calendar information, and any other
data. In iTunes, you can also restore from a backup without deleting data stored on
iPod touch.
Note: Deleted data is no longer accessible via the iPod touch user interface, but is
not permanently erased from your iPod touch until it is overwritten by new data.
For information about permanently erasing all content and settings, see “Resetting
iPod touch” on page 96.
