I swear that at the American Anthropological Meeting, at least one third of the anthropologists that I met had an iPhone. What a bunch of geeks!
In case you didn't know, AT&T will often give you discounted / corporate rates on their monthly service charge if you are an employee of some companies. And most larger schools have these negotiated rates for their students, faculty, staff, and other affiliates.
I should've done this when I signed up for my Jesus-phone but I didn't know until a few months later when a colleague told me. I went down to my local AT&T store and showed them my Yale ID card and they input the discount code in the computer.
Two months later, I'm saving about $12 a month on my service. Not a whole lot, but it adds up to $144 a year.
