Blackberry was all the rage in business. I have never seen anything official about it being the rage among teens.
Nokia phones were in Europe, because using the Nokia writing system for SMS was blazing fast compared to the competition.
But at that time USA didn't have SMS AFAIK.
OK the only place I really heard it was the "rave", was among politicians.
I don't quite get how they could be so popular among teens, as they were quite expensive for a phone for the time.
