1-What it does: It shows the status bar with batery/time/etc within the app instead of the notification center toggle to drop down - It does allow to drop the notifications after
2-What it does: Puts different options once the power button is pressed ( turn off, reboot)
I have seen them in a video recently but i don't remember which one =X
Not sure what you're looking for with 1.
For 2, I know of PowerUp and PowerOptions. I'm not sure if either is iOS 6 compatible.
