  <p>How can I check thought the FB Javascript API if the current user is a fan of some page (not my own app or page, but another specific page)?</p>
  
  <p>I need to check this from within the page inserted into the FB's canvas IFRAME, throught the JS SDK...I need to check whether he has "subscribed" to that page, is a fan of it (clicked "I like it") and possibly if he has put it into his favorites.</p>
  
  <p>Is this possible?</p>
