Apple iPhone has access to AT&T Navigator, the carrier's branded GPS software solution provided by TeleNav, and the first turn-by-turn GPS app for the iPhone. The iPhone's software offers voice-guided turn-by-turn directions, full-color 3D maps, real time traffic updates, live gas prices and more than 10 million points of interest. As it is on all other platforms, such as Android, the software is free, but costs $9.99 per month for unlimited usage.
