title: Rebuild Facebook Javascript Object by just using the signed_request
body: <p>We are stuck into a scenario where the Facebook app we just finished building has to reside inside of a parent iFrame. (This was an unknown to us until now)
  We are wondering if there is an way to easily build the PHP Facebook Object and the JavaScript Facebook Object by only using the 'signed_request' token.
  If not, would it make any sense to try and get the parent iFrame to send us the facebook cookies somehow and us setting those same cookies and then trying to build the objects?</p>
  
  <p>Any help on this would be extremely appreciated as we are stuck very few days before launching.</p>
