Ok, I see no iPhones where I'm at now (Lafayette, Louisiana -- armpit state?). BUT, to get back to Charlotte, I fly to Dallas-Fort Worth Int'l Airport, where EVERYBODY has an iPhone in the airport. It's so WEIRD. I guess since AT&T practically owns Dallas in terms of cell carrier share there. THEN, I got to Charlotte (North Carolina) and again, not very many people at all have iPhones that I see. There's a moderate amount on campus I guess but people seem content with owning whatever model they had when they bought it...people don't rush out to get the new model.
I'll probably be the first iPhone 4 owner I see to be honest. I got a lot of questions when I got my first iPhone, I'm not expecting much less now, especially on my weekend camping trips.
