Windows Phone 8 comes with one of those features for which Apple's Scott Forstall and Google's Matias Duarte might be slapping their foreheads and exclaiming "How didn't I introduce it first!", and it is Live Apps pushing real-time updates to your lock screen wallpaper.
Well, Scott Forstall is gone now,
and we exaggerate, but the idea is pretty neat, and you can set the
lock screen now to display your most needed info before you have even
entered the phone - real-time Facebook updates, scores from the Sports
app, news, weather, and other notifications that 3rd party apps come up
with.
