The iOS family of devices are location-aware, allowing your approximate geographic position to be determined. How this is achieved depends on the hardware present in the device. For example, the original iPhone, all models of the iPod touch, and Wi-Fi-only iPads use Wi-Fi network triangulation to provide location information. The remaining devices can more accurately calculate their position using an on-board GPS chip or cell-phone tower triangulation.
The AIR SDK provides a layer of abstraction that allows you to extract location information in a hardware-independent manner, meaning you can access the information on any iOS device using the same code.
