title: Make an iPhone specific app work on iPad to meet Apple requirements
body: <p>My app has been in the AppStore for a couple of months now and always only worked on iPhone. I recently submitted an update which was rejected because the App does not run on an iPad. The exact reason it was rejected was:</p>
  
  <blockquote>
    <p>Reasons for Rejection:
    2.10: iPhone apps must also run on iPad without modification, at iPhone resolution, and at 2X iPhone 3GS resolution</p>
  </blockquote>
  
  <p>What do I need to do in Xcode to make my app run on an iPad in the little box with the 2X icon?</p>
  
  <p>Any tips instructions will be massively appreciated...</p>
  
  <p><em>EDIT</em>
  This is my info.plist. This is my first App and I think I did initially chose to set it up with "universal" selected. Is there an easy way back for me to rectify this now?</p>
