 Mac: Choose iTunes > Preferences.
 Windows: Choose Edit > Preferences.

Updating and Restoring iPad Software
About Updating and Restoring Software
You can use iTunes to update or restore iPad software.
 If you update, the iPad software is updated. Your downloaded apps, settings, and
data aren’t affected.
Note: In some cases, an update may also include restoring iPad.
 If you restore, the latest version of iPad software is reinstalled, settings are restored
to their default, and all data stored on iPad is deleted, including downloaded apps,
songs, videos, contacts, photos, calendar information, and any other data. If you’ve
backed up iPad with iTunes on your computer, you can restore data from the
backup at the end of the restore process.
Deleted data is no longer accessible through the iPad user interface, but isn’t erased
from your iPad. For information about erasing all content and settings, see “Resetting
iPad” on page 150.
