Settings lets you configure iPod touch, set app options, add accounts, and set other preferences. See other chapters for information about settings for the built-in apps. For example, for Safari settings, see Chapter 15, Safari, on page 71.

Airplane mode

Airplane mode disables the wireless features in order to reduce potential interference with aircraft operation and other electrical equipment.

Turn on airplane mode: Go to Settings and turn on airplane mode.

When airplane mode is on, appears in the status bar at the top of the screen. No Wi-Fi or Bluetooth signals are emitted from iPod touch. You won’t be able to use apps or features that depend on these signals, such as connecting to the Internet. If allowed by the aircraft operator and applicable laws and regulations, you can use iPod touch and apps that don’t require these signals.

If Wi-Fi is available and allowed by the aircraft operator and applicable laws and regulations, go to Settings > Wi-Fi to turn it on. You can also turn on Bluetooth in Settings > Bluetooth.

Wi-Fi

Joining Wi-Fi networks

Wi-Fi settings determine whether iPod touch uses local Wi-Fi networks to connect to the Internet. When iPod touch is joined to a Wi-Fi network, the Wi-Fi icon in the status bar at the top of the screen shows signal strength. The more bars you see, the stronger the signal.

Once you join a Wi-Fi network, iPod touch connects to it whenever the network is in range. If more than one previously used network is in range, iPod touch joins the one last used.

You can also use iPod touch to set up a new AirPort base station that provides Wi-Fi services to your home or office. See Setting up an AirPort base station on page 120.

Turn Wi-Fi on or off: Go to Settings > Wi-Fi. You can:

•• Set iPod touch to ask if you want to join a new network: Turn “Ask to Join Networks” on or off. If “Ask to Join Networks” is off, you must manually join a network to connect to the Internet when a previously used network isn’t available.

•• Forget a network, so iPod touch doesn’t join it: Tap next to a network you’ve joined before. Then tap “Forget this Network.”
