about developing GPS navigation apps for iPhone




The new iPhone 3.0 OS will let developers embed maps in applications with a public API to allow pan and zoom, custom annotations, current location, and geocoding.

They’re enabling developers to use core location as the basis ofturn-by-turn directions applications. Core location gives your location with either GPS, WiFi, or cell tower triangulation. Developers can now build a turn-by-turn direction using real time location from core location. However there’s one catch! B.Y.O.M. Bring your own maps. Due to licensing Apple can not pass on the rights to use built-in maps tiles.

So that’s it. Everybody’s free to develop GPS navigation applications for the iPhone now.
