Did they make the notification center the lock screen by mistake? irritating as f that you can switch to the camera from the notification center but once you are there you can not swipe back to your notifications unless i am missing something. I also find it confusing that you see the lockscreen image instead of the home screen background blurred out.
On top of it says "press home button" instead of swiping up when you are using the notification center but you can still swipe up. Its like they merged the notification center and the lockscreen into one? confusing
Did you install the developer beta without watching the keynote?
