At $1.99 in the Windows Phone 7 Marketplace, SurfCube is hard to pass up. The app takes the stock WP7 browser and builds a 3D cube interface around it. The main browser window is front and center and you can shake or flick to rotate the cube and display SurfCube's other screens -- like settings, tabs, and favorites. SurfCube can also be set to run under your lockscreen, which makes it easier to pick up where you left off.
