title: Do "beta" apps installed on iPod expire when their provisioning certificate does?
body: <p>I have installed an app on
  my iPod touch. Will this app expire when the provisioning certificate does?</p>
  
  <p>EDIT:</p>
  
  <p>I am the developer in this case. I installed it using XCode.   I used a development provisioning profile not a distribution one.  Does this change anything?</p>
