Cool iPhone app

My current favorite is FlightControl by Firemint.  It severley addicting.  The gist that you are a flight controller and you have to land planes and helicopters byt dragging a flight path from the plane to a runway.  Sounds easy, right?  It is, for the first few planes.  Then more planes come, and planes of differing speeds.  Pretty soon, CRASH, a mid air collision.  The graphics are simple but clear, and the interface is nice.  I’m sure I’ll be burning through my battery on this instead of working on the train ;)
