title: UIView Animation: PartialCurl ...bug during rotate?
body: <p>a short question.</p>
  
  <p>I've created an app for the iPad, much like a utility app for the iPhone (one mainView, one flipSideView). The animation between them is UIModalTransitionStylePartialCurl.
  shouldAutorotateToInterfaceOrientation is returning YES.</p>
  
  <p>If I rotate the device BEFORE entering the FlipSide, everything is okay and the PartialCurl is displayed okay.
  But if I enter the FlipSide and then rotate the device, while the UIElements do rotate and position themselves just fine, the actual "page curl" stays with its initial orientation. it just won't budge :)</p>
  
  <p>Is it a known issue? am I doing something wrong?
  Thanks!</p>
