title: @2x images strange issue
body: <p>I’m trying to add a UIImageView programmatically using this code, as I always do:</p>
  
  <pre><code>UIImageView *theImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@“theImage"]];
  [theImageView setFrame:CGRectMake(0.0f, 0.0f, 320.0f, 225.0f)];
  </code></pre>
  
  <p>I’ve added "theImage.png" and "theImage@2x.png” as I always do, but the simulator and my iPhone4 are not able to show the @2x image file. They always show the standard one. Image files are OK (not corrupted) and they’re on the bundle root.
  I’m running Xcode 4.2 and iOS5 SDK.</p>
  
  <p>Any ideas?</p>
