I like to see hands, do you turn off your cellphone in flight?

I have been wondering how many people actually turn off their cell phone in flight. Many people just turn off the screen and don't bother. Others seem very concerned and make sure the phone is truly OFF. I was thinking about this the other day when I was on a flight and my iPhone power button had stopped working, I certainly had mine on. I think we all know it doesn't matter though, with of the devices out there I'm sure each flight has at least 50 devices still on in a plane carrying 200 people.

I bet there is a good portion of us that doesn't bother, can I see hands are you ON or OFF ?
