Notification Center has been updated and improved for iOS 7, and now, it will be available right from the lock screen with no need to unlock the phone first. There's a today view of notifications, with calendar, stocks, other current updates, all of which are available from the lockscreen. And, in keeping with the new design, the Notificiation Center tray has ditched the old look and feel and is now has a translucent background that shows the wallpaper behind.
