title: Transparent color works on the simulator but becomes black on the iPhone
body: <p>I am trying to draw an image that has some transparent regions. 
  I load the image using </p>
  
  <pre><code>image = [UIImage imageNamed:@"testimage.png"];
  </code></pre>
  
  <p>and draw it using</p>
  
  <pre><code>[image drawAtPoint:CGPointMake(0,0)];
  </code></pre>
  
  <p>The UIView on which I draw the image is not opaque (and it has a transparent background color).</p>
  
  <p>The problem is that everything works fine on the simulator, but when I run the app on my iPhone the transparent color becomes black! Can anyone pinpoint my error?</p>
