title: Facebook Requests Dialog on Mobile failed
body: <p>Here is my source code:</p>
  
  <pre><code>FB.ui({method: 'apprequests', to: fbId, message: "hello"}, function(resp){
     if(resp.request_ids){
        $('#req-id').val(resp.request_ids);
          $('form').submit();
     } else {
         return false;
     }
  });
  </code></pre>
  
  <p>And here is what I get when I run it in a browser with User Agent set to iPhone:</p>
  
  <pre><code>An error occurred. Please try again later.
  </code></pre>
  
  <p>It also popup a window to display the message which is not wanted. I've tried to add "display:touch" parameter without any fortune.</p>
  
  <p>Did anyone encountered this before?</p>
  
  <p>Thanks,
  Green</p>
