In the demos/screenshots it looked like fast switches where you could enable-disable things (wifi, bluetooth, airplane, flashlight), nothing more.

edit: http://www.apple.com/ios/ios7/features/ confirms it

> Turn on or off Airplane mode, Wi-Fi, Bluetooth, and Do Not Disturb. Lock your screen’s orientation or adjust its brightness. Play, pause, or skip a song. Connect to AirPlay-enabled devices. And quickly access your flashlight, timer, calculator, and camera.

(emphasis mine)

Are you sure that means you can easily switch a locked phone to an untrusted network?

It looked like you could turn it on and off.
