title: iphone large icon 512x512 with border glitch?
body: <p>I just uploaded my first iPhone app. The app icon has a border, sort of like the "settings" icon. However, when I upload my large icon in iTunes connect, there are some weird white edges in the corners. It appears that they might use a smaller corner radius or something. How can I make sure it will display correctly on the apple store?
  The image is a jpeg with no transparency.</p>
