Disabled iPhone
If iPhone is disabled because you forgot your passcode or entered an incorrect passcode too
many times, you can restore iPhone from an iTunes or iCloud backup and reset the passcode. For
more information, see
Restore iPhone on page 178.
If you get a message in iTunes that your iPhone is locked and you must enter a passcode, see
support.apple.com/kb/HT1212 .
Back up iPhone
You can use iCloud or iTunes to automatically back up iPhone. If you choose to back up using
iCloud, you can’t also use iTunes to automatically back up to your computer, but you can use
iTunes to manually back up to your computer. iCloud backs up to iPhone daily over Wi-Fi, when
it’s connected to a power source and is locked. The date and time of the last backup is listed at
the bottom of the Backup screen.
iCloud backs up your:
Purchased music, movies, TV shows, apps, and books
Photos and videos taken with iPhone (if you use iCloud Photo Library beta, your photos and
videos are already stored in iCloud, so they won’t also be part of an iCloud backup)
iPhone settings
App data
Home screen, folders, and app layout
Messages (iMessage, SMS, and MMS)
Ringtones
Note: Purchased content is not backed up in all areas.
Turn on iCloud backups. Go to Settings > iCloud, then sign in with your Apple ID and password
if required. Go to Backup, then turn on iCloud Backup. To turn on backups in iTunes on your
computer, go to File > Devices > Back Up.
