If you're feeling too boxed in with Internet Explorer on your Windows Phone, consider checking out SurfCube, which brings your browsing experience outside the box -- literally. Since we last visited the app, an ad-supported version was introduced alongside the $1.99 paid version, allowing users to spin the browser without any commitment. This useful (and entertaining) functionality was enough to help the developer score a Microsoft Innovation Award for smartphone applications -- a feat it has accomplished twice before. Fresh off its win, SurfCube 3.0 debuted with numerous bug fixes, performance improvements, and -- perhaps most importantly -- YouTube support. It also claims to have the best tab support of any WP7 browser, a point you can judge for yourself in the video just past the break.
