Microsoft is introducing a new lock screen on Windows Phone 8 that can be customized thanks to the Live App infrastructure. What does this mean for you? Well, your lock screen just became a lot more useful, as you can have it display things like recent photos, sports scores, Facebook updates from close friends, and more. Not the most groundbreaking feature in the world, but it's another way that Windows Phone 8 allows you to customize your phone in a personal way, bringing real-time updates to the first screen you see when your turn on your phone.
