I'm already an AT&T customer and I have a FAN discount through my employer. When I go through the motions of purchasing an iPhone online through AT&T, it applies the discount to my new data plan. I'd really, really prefer to buy it at the Apple store, but when I go through the motions using their "order it online and pick it up in the store" feature, it indicates I'll be paying full price for the data plan. Has anyone done this? Will AT&T pick up that I have a FAN and apply the discount anyway? If not, will there be any problem going back and having it applied again?
