Screen flip?

So

function FixedUpdate () { 
   if (iPhoneInput.orientation == iPhoneOrientation.LandscapeLeft) 
      print("left"); 
   if (iPhoneInput.orientation == iPhoneOrientation.LandscapeRight) 
      print("right"); 
}

This lets you tell what landscape orientation the device is in, how do I get the screen to actually flip round?

iPhoneSettings.screenOrientation = iPhoneScreenOrientation.LandscapeLeft;

or

iPhoneSettings.screenOrientation = iPhoneScreenOrientation.LandscapeRight;
