title: Installing Different versions of iPhone simulator
body: <p>I recently installed a new OS X on my mac, and installed XCode on it. It provided me only with iOs 6.0 simulator ( and maybe only iPhone 5, I don't really know how to change the simulated device ).</p>
  
  <p>I have a couple of problems I encountered when porting an iPhone 4 project to this XCode, and I want to see if the problem is caused because of new changes in iOS 6/iPhone 5 or simply the code is wrong.</p>
  
  <p>For that reason I want to be able to run the simulator with iOs 4 / iPhone 4, But I can't find a way to do that.</p>
  
  <p>Any suggestions?</p>
