I'm upgrading from an E71x
Way before that (heh, August of last year) I bought an iPhone 3G, but I got a cushy job at an at&t authorized retailer and had to forgo my iPhone to switch to the Employee Plan, well 4 different phones later I figured the discount wasn't worth it and switched back to a consumer plan and await my 3Gs.
e71/blackberry/WinMo Employee Plan (2,000 min, unlim text/data) 30.00 a month
my new iPhone bill (450 min, unlim text/data) like 90.00 a month
I'm either stupid or particular, I say both.
