File sharing

You can use iTunes to transfer les between iPhone and your computer. You can also view les

received as email attachments on iPhone. See Reading mail on page 51. If you have the same

apps that work with iCloud on more than one device, you can use iCloud to automatically keep

your documents up to date across all your devices. See iCloud on page 15.

Transfer les using iTunes: Connect iPhone to your computer using the included cable. In

iTunes on your computer, select iPhone, then click the Apps button. Use the File Sharing section

to transfer documents between iPhone and your computer. Apps that support le sharing

appear in the File Sharing Apps list in iTunes. To delete a le, select the le in the Files list, then

press the Delete key.

Security features

Security features help protect the information on iPhone from being accessed by others.

Passcodes and data protection

For security, you can set a passcode that you must enter each time you turn on or wake up

iPhone, or when you access the passcode lock settings.

Setting a passcode turns on data protection, which uses your passcode as the key for encrypting

mail messages and attachments stored on iPhone. (Some apps available from the App Store may

also use data protection.) A notice at the bottom of the Passcode Lock screen in Settings shows

that data protection is enabled.

Important: On an iPhone 3GS that didn’t ship with iOS 4 or later, you must also restore iOS

software to enable data protection. See Updating and restoring iPhone software on page 152 .

Set a passcode: Go to Settings > General > Passcode Lock, then tap Turn Passcode On and enter

a 4-digit passcode.

Use a more secure passcode: To increase security, turn o Simple Passcode and use a longer

passcode with a combination of numbers, letters, punctuation, and special characters.

To unlock iPhone when it’s protected by a combination passcode, you enter the passcode using

the keyboard. If you prefer to unlock iPhone using the numeric keypad, you can set up a longer

passcode using numbers only.

Prevent access to Siri when iPhone is locked: Go to Settings > General > Passcode Lock, then

turn Siri o.

Prevent voice dialing when iPhone is locked: Go to Settings > General > Passcode Lock, then

turn Voice Dial o. (Available only when Siri is turned o in Settings > General > Siri.)

See Passcode Lock on page 136 .
