Backing Up iPhone 
iTunes creates backups of settings, downloaded applications, and other information 
on iPhone. You can use a backup to restore these items to your iPhone after a software 
restore or to transfer the information to another iPhone. 
Backing up iPhone or restoring from a backup is not the same as syncing content 
and other items (such as music, podcasts, ringtones, photos, videos, and applications 
that you download via iTunes) with your iTunes library. Backups include settings, 
downloaded applications, and other information that resides on iPhone. You can 
restore these items from a backup using iTunes, but you may also have to sync your 
iTunes library content again. 
Creating Backups 
Backups can be created in the following ways: 
  
Once iPhone has been configured to sync with a particular computer, iTunes 
automatically makes a backup of iPhone on that computer when you sync. iTunes 
won’t automatically back up an iPhone that is not configured to sync with that 
computer. If you have configured iPhone to automatically sync with iTunes on a 
specific computer, iTunes will back up iPhone every time you connect it to that 
computer. Automatic syncing is turned on by default. iTunes only makes one backup 
each time you connect, even if you sync multiple times before disconnecting. 
 
If you choose to update the software on iPhone, iTunes will back up iPhone 
automatically, even if it is not configured to sync with iTunes on that computer. 
  
If you choose to restore the software on iPhone, iTunes asks if you want to back up 
iPhone before restoring. 
If you use a Bluetooth headset or car kit with iPhone and you restore settings, you 
must pair the Bluetooth device with iPhone again to use it. 
Restoring from a Backup 
You can restore the settings, downloaded applications, and other information from a 
backup, or use this feature to transfer these items to another iPhone. 
Restore iPhone from a backup: 
1  
Connect iPhone to the computer you normally sync with. 
2  
In iTunes, select iPhone in the sidebar and click the Summary tab. 
3  
Click Restore to reinstall the iPhone software, restore its default settings, and delete 
data stored on iPhone. In iTunes 7.7, you can also restore from a backup without 
deleting data stored on iPhone.
