Customize Lock Screen
While it?s been easy to customize your lock screen with static images, WP8 lets you customize the lock screen with app data and/or live tile information. Just go to Settings | Lock Screen | ?Open this app to let it make changes? | click the APP button, go to your app (say the HTC app that includes newsfeeds, weather, stocks), pick the screen you?d like to have as your new lock screen and you?re done. This works for all apps enabled for this feature like music (have your artist display on your lock screen while music plays), Bing (Bing?s desktop of the day), Facebook, etc. Mine is set to HTC?s local weather conditions.
