title: UIImagePickerController always pics 640x640 image
body: <p>When I present a UIImagePickerController in my iPhone App, it always comes up with a white square with a frame around it, and the user has can zoom in and out of an image and make it fit within the white square. Whatever they fit in the white square is what is returned to:</p>
  
  <pre><code>- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)info
  </code></pre>
  
  <p>and it is always 640x640.</p>
  
  <p>Why can't the user select an entire image? Why does this white square even come up?</p>
