How to move a MKAnnotation without adding/removing it from the map?

Question

Is it possible to move the coordinate of a MKAnnotation without adding and removing the annotation from the map?

Answer 1

Take a look at my MapKitDragAndDrop sample, it allows you to update MKAnnotation and move MKAnnotationView on both iPhone OS 3 and iOS 4 (will use built-in dragging support).
