title: Twitter Bootstrap navigation working on desktop but not mobile
body: <p>I'm using the collapsing navigation menu from Twitter Bootstrap as demoed here: <a href="http://twitter.github.com/bootstrap/examples/starter-template.html" rel="nofollow">http://twitter.github.com/bootstrap/examples/starter-template.html</a></p>
  
  <p>It works fine when I test it in browsers on the desktop by resizing the browser window but nothing fires when I test it on my mobile (iPhone 4s). </p>
  
  <p>The sample page above from Bootstrap works on my mobile so I've been comparing both and can't figure out what's causing it not to fire.</p>
  
  <p>Anyone run into this problem before?</p>
