Setup and activation
To set up and activate iPhone, turn on iPhone and follow the Setup Assistant. The Setup Assistant
steps you through the setup process, including connecting to a Wi-Fi network, signing in with or
creating a free Apple ID, setting up iCloud, turning on recommended features such as Location
Services and Find My iPhone, and activating iPhone with your carrier. You can also restore from an
iCloud or iTunes backup during setup.
Activation can be done over a Wi-Fi network or, with iPhone 4S, over your carrier’s cellular network
(not available in all areas). If neither option is available, you need to connect iPhone to your
computer for activation.
Connecting iPhone to your computer
If you don’t have Wi-Fi or cellular access, you may need to connect iPhone to your computer in
order to complete activation. Connecting iPhone to your computer also lets you sync information,
music, and other content with iTunes. See “Syncing with iTunes” on page 18.
Connect iPhone to your computer: Use the Dock Connector to USB Cable provided with iPhone.
Connecting to the Internet
iPhone connects to the Internet whenever necessary, using a Wi-Fi connection (if available) or
your carrier’s cellular network. For information about connecting to a Wi-Fi network, see “Wi-Fi” on
page 15 8 .
Note: If a Wi-Fi connection to the Internet isn’t available, certain iPhone features and services
may transfer data over your carrier’s cellular network, which may result in additional fees. Contact
your carrier for information about your cellular data plan rates. To manage cellular data usage, see
“Network” on page 163.
