Since I wanted to buy two iPhones (one for my wife and one for me), I didn't have the option of ordering online, so I went to the local AT&T store and pre-ordered there. They seemed pretty confident that as long as I was in line at 7 AM on the 19th that I'd get my phones that day. Did anyone else also pre-order at a brick & mortar AT&T store? Did the salesperson guarantee that you'd get your phone on the 19th?
