title: iOS "Private"/AdHoc App Store - principle of operation
body: <p>How do the "private" app stores operate from a technological point of view?</p>
  
  <p>For example, this store used in Iran: <a href="http://sibapp.com/" rel="nofollow noreferrer">http://sibapp.com/</a></p>
  
  <p>My questions are:</p>
  
  <ol>
  <li>Do they require jailbreak?</li>
  <li>How the apps are distributed, compared to the standard App Store.</li>
  </ol>
