Now you can have one of the coolest programs being developed for the mobile device, using the iPhone SDK, has got to be iPhone Earth.
“Earthscape” is developing the app to bring Google (NSDQ: GOOG) Earth-like functionality to the iPhone and, from the looks of it, iPhone Earth is sure to be a killer application when it goes live. It may not recommend the most functionality from an iPhone application, but iPhone Earth definitely has the “cool” factor that will be hard to ignore.

Now using the iPhone’s multi-touch screen, iPhone Earth permits the user to pan around and zoom in (through the pinch gesture) on different portions of a 3D globe.
Also, iPhone Earth leverages the accelerometers built in to the iPhone to tilt and rotate the map-view as you like.
