title: Anyone else having trouble updating XCode to 4.3.1?
body: <p>I have two MacBook Airs (One is the newest version).  On both of them I have tried to install the new version of XCode via the Mac App Store.  Both of them downloaded and indicate that it installed, but XCode still reports 4.2.1 and I can't deploy apps to my phone because it is running 5.1 and the SDK is missing from XCode.</p>
  
  <p>Anyone else having similar issues?</p>
