Apple iPod touch iOS 5.1 - Manual (Page 102)

Some apps have additional options. For example, Messages lets you specify how many times the
alert sound is repeated, and whether message previews are included in the notification.
Location Services
Location Services lets apps such as Reminders, Maps, Camera, and third-party location-based apps
gather and use data showing your location. The location data collected by Apple isn’t collected
in a form that personally identifies you. Your approximate location is determined using local Wi-Fi
networks (if you have Wi-Fi turned on). To conserve battery life, turn location services off when
you’re not using it.
When an app is using Location Services, appears in the status bar.
Every app and system service that uses Location Services appears in the Location Services settings
screen, showing whether Location Services is turned on or off for that app or service. If you don’t
want to use Location Services, you can turn it off for some or for all apps and services. If you turn
Location Services off, you’re prompted to turn it on again the next time an app or service tries to
use it.
The location data collected by Apple doesn’t personally identify you. If you have third-party apps
on iPod touch that use Location Services, review the third party’s terms and privacy policy for
each app to understand how it uses your location data.
Turn Location Services on or off: Go to Settings > Location Services.
VPN
VPNs used within organizations let you communicate private information securely over a
non-private network. You may need to configure VPN, for example, in order to access your work
email. This setting appears when you have VPN configured on iPod touch, lets you turn VPN on
or off. See “Network” on page 103.
