Turn Internet Tethering on or off: Choose General > Network > Internet Tethering, then turn Internet Tethering on or off.

Internet Tethering lets you share iPhone’s Internet connection with a computer connected via USB or Bluetooth (not available in all regions). Follow the onscreen instructions to complete the setup. Additional fees may apply. See “Using iPhone as a Modem” on page 42.

Add a new VPN configuration: Choose General > Network > VPN > Add VPN Configuration.

VPNs used within organizations allow you to communicate private information securely over a non-private network. You may need to configure VPN, for example, to access your work email on iPhone.

iPhone can connect to VPNs that use the L2TP, PPTP, or Cisco IPSec protocols. VPN works over both Wi-Fi and cellular data network connections.

Ask your network administrator which settings to use. In most cases, if you’ve set up VPN on your computer, you can use the same VPN settings for iPhone.

Once you’ve entered VPN settings, a VPN switch appears in the Settings menu that you can use to turn VPN on or off.

VPN may also be automatically set up by a configuration profile. See “Installing Configuration Profiles” on page 18.

Change a VPN configuration: Choose General > Network > VPN and tap the configuration you want to update.

Turn VPN on or off: Tap Settings and turn VPN on or off.

Delete a VPN configuration: Choose General > Network > VPN, tap the blue arrow to the right of the configuration name, and tap Delete VPN at the bottom of the configuration screen.

Bluetooth

iPhone can connect wirelessly to Bluetooth devices such as headsets, headphones, and car kits for music listening and hands-free talking. See “Bluetooth Devices” on page 55.

Turn Bluetooth on or off: Choose General > Bluetooth and turn Bluetooth on or off.

Location Services

Location Services allows applications such as Maps Camera, and Compass to gather and use data indicating your location. Location Services doesn’t correlate the data it collects with your personally identifiable information. Your approximate location is determined using available information from cellular network data, local Wi-Fi networks (if you have Wi-Fi turned on), and GPS (iPhone 3G or later; GPS may not be available in all locations).
