title: Lion + Xcode 3.2.3 starting problem
body: <p>I just got a book for iPhone programming from the library which is based on Xcode 3.x so I want to start with that. Fortunately I updated from SnowLeopard to Lion with Xcode already installed so I didn't have problems to get it installed or running in the first place.</p>
  
  <p>So I read through the HelloWorld-Example and as soon as I try to start interface builder I get the message:</p>
  
  <pre><code>This version of Interface Builder does not support documents of type "Interface Builder Cocoa Touch Document (XIB 3.x)" targeting "iPhone/iPod touch
  </code></pre>
  
  <p>I've Xcode 3.2.3 installed and have a clue how to change to something other than XIB 3.x to make this work.</p>
  
  <p>Any suggestions?</p>
