== Core Location Framework (CoreLocation.framework) ==

The Core Location framework allows you to obtain the current geographical location of the device (latitude and longitude) and compass readings from with your own applications. The method used by the device to provide coordinates will depend on the data available at the time the information is requested and the hardware support provided by the particular iPhone model on which the app is running (GPS and compass are only featured on recent models). This will either be based on GPS readings, Wi-Fi network data or cell tower triangulation (or some combination of the three).
