How to get the old enter passcode screen with ios7?

How do i get the old iphone "enter passcode" screen? Don't like the new one. See the link for the difference:

Once you download iOS 7, you can't change back to iOS 6

Unfortunately, this can't be done.
You also can no longer downgrade back to 6.1.3
This new passcode screen is the updated version of the one you like and, unfortunately, is permanent.
