title: facebook fb:login-button for mobile web
body: <p>I'm trying to fb:login-button work for mobile web, a la: <a href="http://developers.facebook.com/docs/guides/mobile/" rel="nofollow">http://developers.facebook.com/docs/guides/mobile/</a> </p>
  
  <p>However, I'm not sure where to add this code:  <code>&amp;display=touch</code></p>
  
  <p>My FBML is the standard: </p>
  
  <pre><code>&lt;fb:login-button autologoutlink='true' perms='user_about_me,email'&gt;&lt;/fb:login-button&gt;
  
  &lt;div id="fb-root"&gt;&lt;/div&gt;
  &lt;script&gt;
      window.fbAsyncInit = function() {
          FB.init({ appId: 'XXXXXXX', status: true, cookie: true, xfbml: true });
          FB.Event.subscribe('auth.login', function() {
              location.href = "....";
          });
      };
      (function() {
          var e = document.createElement('script');
          e.type = 'text/javascript';
          e.src = document.location.protocol +
        '//connect.facebook.net/en_US/all.js';
          e.async = true;
          document.getElementById('fb-root').appendChild(e);
      } ());
  &lt;/script&gt;
  </code></pre>
  
  <p>Any ideas?</p>
