title: iPhone app crashing
body: <p>I've had three users of an app I've published say that it crashes. I've run it in Instruments and there are no leaks and no over released objects either. I've been using the app myself quite a bit for at least 2 weeks and it doesn't crash for me.</p>
  
  <p>I was wondering if anyone had any tips on how to problem solve an issue like this. </p>
  
  <p>One thing that I'm suspicious of is the Millenial Media ads that I have running in some of the views. A Build and Analyze reveals 13 issues and they all pertain to the ad API</p>
