It seems to be an average for teenage girls, when I was in high school thats what I saw but now they have outlawed cellphones in the public schools here, probably just for that reason.
Outlawed as in banned by the school? I know the technical policy for my high school was that we had to leave them in our lockers. Of course, nobody actually did that. It was entertaining to see teachers catch students though.
As in banned, if you are seen with a cell phone on campus it is taken away and brought to the office for your parents to pick up the first time, second offense it stays in the office for a month and 3rd for a year, at least at my brothers school it is that way.
In reality, though, your parents could always come and pick it up. If they weren't allowed to, it would be theft. I just imagine that after the first offense they don't bother calling your parents, and just expect your shame to prevail over asking them to bail it out.
