Apple iPod touch iOS 3.1 - Manual (Page 118)

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 iPod touch.
iPod touch can connect to VPNs that use the L2TP, PPTP, or Cisco IPSec protocols.
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 iPod touch.
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 15.
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
iPod touch can connect wirelessly to Bluetooth headphone devices for music listening
(not available on first-generation iPod touch). See “Bluetooth Headphones” on page 34.
Turn Bluetooth on or off: Choose General > Bluetooth and turn Bluetooth on or off.
Location Services
Location Services allows applications such as Maps 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 local Wi-Fi networks (if you have Wi-Fi turned on).
You can turn Location Services off if you don’t want to use this feature. If you turn
Location Services off, you’ll be prompted to turn it on again the next time an
application tries to use this feature.
Turn Location Services on or off: Choose General > Location Services and turn
location services on or off.
To conserve battery life, turn Location Services off when you’re not using it.
Auto-Lock
Locking iPod touch turns off the display to save your battery and to prevent
unintended operation of iPod touch.
