While the lock screen on Windows Phone is pretty informative, it’s not perfect especially for those who love hacking. You can surely see, at a glance, the current time, missed calls, incoming texts or e-mail and such but with this beta software you’ll be able to set some widgets to your lock screen.
You need to have a “rooted”/unlocked phone to take this beta for a spin. You can chose between your own wallpaper as well as the one provided by Bing, after which you can add some widgets (like weather, RSS reader, memory usage and hopefully more to come). Check out the video of the app in action below and make sure to follow the source link for download and more information.
