The document discusses location tracking APIs available on iOS devices, including Significant Location Changes and Region Monitoring. Significant Location Changes allows detecting location changes of 300-500 meters on iPhone 3GS and later, while Region Monitoring allows monitoring when a device enters or exits user-defined areas and is available on iPhone 4 and later. Examples are given of how to implement these APIs through a location manager delegate.
