title: Installing different versions of the same iPhone project?
body: <p>While I'm prototyping games, I frequently need to go back to compare with older versions, to better get a feel of if I'm on the right track or not. But it's a lenghty process to have to check out the old version and re-export everytime I need to check a specific version. It'd be so much smoother if I could simply launch different versions.</p>
  
  <p>How can I have multiple versions of the same project installed on the device?</p>
