A few months ago I had just taken my seat in FC on a Continental flight when a guy yapping on his cellphone started to put his stuff away above me. He leaned over toward me, talking very loudly on the phone. I gave him the nonverbal "please quiet down just a bit" sign (palm down, hand moving slightly up & down); he took umbrage at that and asked me what the problem was.
I do not want cellphones allowed during flight, as many users are completely inconsiderate. I suspect that their use would cause even more aggravation than already exists on many flights.
