I heard some AT&T stores are making a kind of wait list for people calling in. Either that or make sure you get to the store at about 4:30 as I also heard that's when the AT&T stores will close their doors to set up the iPhone displays, accessories and open up the shipment boxes.
What I'm not sure about is the rates. Are they using the same ATT plans that are already in place? I also thought I saw some rumor that there wasn't necessarily going to be a mandatory 2 year contract. Finally, isn't each store supposed to get a fairly large allotment?
Actually, the number of available iPhones is standing at 3 million units nation-wide. The current estimate is around 40 phones per AT&T store and a higher amount for the Apple Stores themselves
