title: Why am I seeing "This application does not support this device's CPU type"?
body: <p>When trying to build and install an application on an iPod running iOS 4.2.1, I'm seeing the error</p>
  
  <blockquote>
    <p>This application does not support this device's CPU type</p>
  </blockquote>
  
  <p>I'm trying to build the application using xcode 4.3, as well as xcode 4.4, and still seeing this. What can cause this and how can I fix it?</p>
