title: mobile site - reset the viewport on orientation change
body: <p>I have a mobile page that is 590px wide. So I set the viewport like this:</p>
  
  <pre><code>&lt;meta name = "viewport" content = "width = 590"&gt;
  </code></pre>
  
  <p>When I first visit the page either in portrait or landscape - it looks fine. The page fills the width exactly. But when I change orientation the viewport doesn't change. When I go from portrait to landscape the viewport is wider than the 590px, and vice versa.</p>
  
  <p>Tested only on Galaxy S2</p>
