Facebook is looking for volunteers to use its new beta app and recommend changes to make it better. The announcement was made via the Windows.com blog and calls upon "all tinkerers" who "love Facebook and enjoy playing around with pre-release software."
The app is available through the Windows Phone Store, though it won't show up in normal search results. You'll need to use this direct link to the app to be able to download and use it. They note that those who don't like app crashes should steer clear of this app as it is a beta product.
As you'll see, the app is undergoing a major redesign and now includes several much-requested features, including new support for high-res photos, post sharing, and Facebook Timeline. Once you've put the beta app through its paces, we hope you'll pass along bug reports, feature requests, and other feedback by going to Settings>About in the app. You can also post a Store review. Your comments and suggestions will inform future releases.
