title: Does apple apply the app icon gloss effect and corner rounding on every icon?
body: <p>The iTunes Connect Developer Guide says that the developer must provide a whole bunch of different icon sizes. But I only know from the "normal" app icons (57x57, 114x114) that the device applies the gloss effect and corner rounding automatically.</p>
  
  <p>But how about those other icons? How about the 512x512 iTunesArtwork.png icon? Are the effects applied automatically? Must this icon be shipped inside the bundle of the app? Is there any way to see it "live" how it finally looks, when those effects are applied?</p>
  
  <p>I slightly remember that there was a tool from apple that applied those effects to an icon, so you could see them. Does anyone know more details about this?</p>
