Push.js doesn't work in iOS simulator
I'm developing a Phonegap application. Push.js works (loads other pages into the `.content` element) in the Android emulator, in Google Chrome web browser but not in the iOS simulator.

```
<a class="tab-item active" href="about.html" data-transition="slide-in">
    <span class="=icon icon-home"></span>
    <span class="tab-label">About</span>
</a>
```
