The rather important and major upgrade for WebApps is now available. We previously looked at the Windows Phone app last month when we were able to publish a sneak peek at the new features, including Live Tiles for individual web applications.
If you're not familiar with the app, it enables consumers to enjoy HTML experiences on Windows Phone. As well as the new Live Tiles, the team has also introduced wide tiles and voice search. Here's a quick video of what's new in version 1.4:
You can download WebApps from the Windows Phone Store. It's worth noting that the new feature may be delayed as it's an in-app purchase, so fear not if you're unable to purchase the optional upgrade for a day or few (though if you have already got the "pro pack" you're absolutely fine and will have the new tiles at no extra cost).
