As promised, the new Windows Phone 8.1 Live Lock Screen is now available.
Want to truly personalize your lock screen? Live lock screen lets you choose from 6 new lock screen layouts to add a distinctive touch to your Windows Phone. Each layout has a revamped design for the time, date, and notifications, as well as a unique unlock animation. You can also cycle through multiple background images throughout the day to keep your lock screen fresh—or just get the latest incredible image from Bing every morning.
