title: Testing different screen resolutions in Universal (iPad,iPhone,iPod) app development
body: <p>I notice when submitting a Universal app to the app store, there are various screen resolutions to support.  I think iPhone/iPod: 320x460, 320x480, 640x960 and iPad 768x1024.</p>
  
  <p>When I specify Universal app development in Xcode, the simulator has a resolution of 320x480.  To view 768x1024 screen resolution, I can change the target setting to iPad, but how to test 320x460 and 640x960 resolutions?</p>
  
  <p>My default solution is to target iPad, and manually hack my code, e.g.: <code>SCREEN_WIDTH=640, SCREEN_HEIGHT=960;</code> but surely there should be a setting on the simulator for this!?</p>
  
  <p>In a related question, is there any way to get screen captures off the simulator (apart from command-shift-3 and cropping the resulting image)?</p>
  
  <p>Thanks in advance.</p>
