Date formatting for ISODate string fails on Android 2.1 stock browser

The following does not work on the Android 2.1 stock browser.

```
<!doctype html>
<html>
  <body ng-app>
    <span>{{ '2013-03-12T06:26:08.832Z' | date }}</span>       
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.min.js"></script>
  </body>
</html>
```

It prints "Mar NaN, NaN" instead of "Mar 12, 2013".

Problem occurs with both Angular 1.0.5 and 1.1.3.
