The error is due to the fact that you're using the id #whoatnet-to-itunes
for two elements:
<div class="tryme" id="whoatnet-to-itunes">...</div>
<div class="iphone" id="whoatnet-to-itunes"></div>
This isn't valid and means that you're attaching a click and hover event to both the iPhone and the bubble. Remove the ids from both of them change the selector from:
$('.home-content #whoatnet-to-itunes')
to $('.home-content .iphone')
.
The hoverIntent code would then look like this:
$('.home-content .iphone').click(function() {
window.location = home.itunesLink + this.id;
}).hoverIntent(toggleFade);
