title: <input type="number"/> is not showing a number keypad on iOS
body: <p>According to <a href="http://developer.apple.com/library/safari/#documentation/AppleApplications/Reference/SafariHTMLRef/Articles/InputTypes.html">Apple's documentation</a> when I setup an input element with a type of <code>number</code> I should get a number keypad.</p>
  
  <pre><code>&lt;input type="number"/&gt;
  </code></pre>
  
  <blockquote>
    <p><code>number</code>:
    A text field for specifying a number. Brings up a number pad keyboard in iOS 3.1 and later.</p>
  </blockquote>
  
  <p>Looks damn near impossible to mess up.  However, when I view this simple fiddle on my iPhone or the simulator (both iOS6) the number keypad does not appear, and I get the standard alphabetic keyboard instead.</p>

  <p>What on earth could I possibly have messed up here?</p>
