title: How can I test app on older iPhone 3G with iOS v 4.2.1
body: <p>I  have been testing my app on my iPhone 4S and my wife's iPhone 3GS.  I would also like to test it on the older iPhone 3G running iOS 4.2.1 (the highest version it will support).</p>
  
  <p>When I connect the 3G to my Mac and attempt to provision it, I get two error messages:</p>
  
  <p><strong>Could Not Support Development</strong></p>
  
  <p>and</p>
  
  <p><strong>Xcode cannot find the software image to install this version</strong></p>
  
  <p>I am using the latest version of xCode (v. 4.4.1).</p>
  
  <p>Is there some place to find the missing 'software image' in order to test my app on the 3G and older iOS devices?</p>
  
  <p>If not, how does one know what devices the app will work with?</p>
  
  <p>I do note that the newer iPhones that run iOS5 and above also support Automatic Reference Counting (ARC). I have checked the ARC button whenever I created a new project. Does one have to abandon ARC if one wants their app to work on an older pre iOS5-capable device?</p>
