title: Track Facebook Wall Post existence through iPhone app
body: <p>I have a general question. I am working on an iPhone App where we post certain things on a user's Facebook wall. We want to track if the exact post made the user still exist the day after. Basically, I want to find out if its possible to check whether a certain post that is made through our App still exist on Facebook or not?</p>
  
  <p>If anyone has an answer for this that would be great!</p>
