VisualMap is a simple easy to use tool for iPhone 3GS/4 only. Works better with iOS4
Hint: Try turning 3G off - and should get a much better fix. This is not streetview.
What does it do?
The application shows you the view through the camera alongside a correctly oriented map...as you rotate around the map view changes - so it is easy to see where you are in the world and what is around you.
You can zoom and pan the map as you would with a normal map.
VisualMap makes use of the iPhone 3GS compass feature and requires a 3GS iPhone to work. The accuracy of the GPS location will depend upon the GPS signals being received.
