File sharing You can use iTunes to transfer files between iPhone and your computer. You can also view files 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 files 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 file sharing appear in the File Sharing Apps list in iTunes. To delete a file, select the file 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 off 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 off. Prevent voice dialing when iPhone is locked: Go to Settings > General > Passcode Lock, then turn Voice Dial off. (Available only when Siri is turned off in Settings > General > Siri.) See Passcode Lock on page 136. Chapter 3 Basics 33
