title: How to set custom icon for beta version
body: <p>Recently my brother showed me his invite to beta test an app. This was being done via HockeyApp. Once he installed this version, it had a nice "BETA" stripe on the icon. The App Store version had the original logo. And according to a picture shown by the developer, he had another icon saying "DEV".</p>
  
  <p>I went looking for tutorials on how to do this and came across <a href="http://engineering.circle.com/different-app-icons-for-beta-dev-and-release-builds/" rel="nofollow">this</a>. It works for the dev and App Store part but fails on TestFlight, which shows me the App Store logo. Also, changing the Bundle Identifier causes me not to test my in app purchase (logically). Is there any other way?</p>
  
  <p>Thanks!</p>
  
  <p><strong>Edit</strong>: I would like a beta app icon for TestFlight via iTunes Connect.</p>
