title: Rotating only the MapView's content
body: <p>I am trying to rotate a map view in my app according the the user's current route. (I don't like to use the built in compasse because only 3GS uses it and it suffers too much interference from other machines, i.e. your own car.).</p>
  
  <p>the CGAffineTransformMakeRotation method will rotate the Whole Map View, so the Google Logo will not be in the lower right of the screen anymore.  Also all Annotation Views will rotate and look weird on the App.</p>
  
  <p>Does anyone knows how to rotate just the content (streets drwaings) of the MkMapView?</p>
  
  <p>Thanks</p>
