body: <p>How to support IOS6 and IOS7 app icons and launch images in the same app?  </p>
  
  <p>I have noted IOS7 has <a href="https://developer.apple.com/library/prerelease/ios/documentation/UserExperience/Conceptual/MobileHIG/IconMatrix.html#//apple_ref/doc/uid/TP40006556-CH27-SW1" rel="nofollow">new Icon sizes pere here</a>, however it's not clear to me how you would best ensure IOS 6 and IOS 7 devices are supported?  So how would you do this, e.g.</p>
  
  <p>a) have to put both IOS6 and IOS7 app icon &amp; launch images in?<br>
  b) or just put IOS7 icons/launch images in and IOS6 devices will handle this ok?</p>
  
  <p>NOTE: I'm using Corona SDK as my dev platform (not XCode / ObjectiveC)</p>
