title: HOWTO remove device tokens received by Apple APNS feedback
body: <p>I am successfully fetching Apple APNS feedback data via PHP. The structure that I am getting (after some processing) looks something like this:</p>
  
  <p>timestamp</p>
  
  <p>device token </p>
  
  <p>My question is how to know which of the device tokens should I remove from my database and stop sending notifications to them.</p>
