title: Launch image doesn't update
body: <p>I'm using Xcode 4.3.1. Adding launch image is pretty simple -- just drag the image to the Project->Summary->Launch Images window.</p>
  
  <p>So I set a launch image before and it worked. But when I dragged a different image and run the app on my iPhone again, the launch image still remain the same as the old one. Even after I delete the launch image from the Launch Images window, the old image still shows up upon launching.</p>
  
  <p>I've tried clearing the build as well. Didn't work.</p>
  
  <p>Help please. Very much appreciated!</p>
