Ability to control lock screen of iPhone running iOS 7 with bluetooth keyboard?
I upgraded the iPhone. And yes, the bluetooth keyboard still works to unlock the phone (just not iPad), and unlike in iOS 6 it jumps straight past the "slide to unlock" to the passcode screen.

Interestingly, though, if I show the slide to unlock screen, "esc" no longer swipes it to the passcode screen.

Spotlight/search button on keyboard is, by the way, useless now also on the iPhone.
