I had an order with ATT and got one of the launch day dates, but had to cancel it because ATT treated me so bad and I decided stick with my apple app store order. Long story short, there was a glitch on the ATT site and ATT app that wouldn't allow me to pay in full or put any money down towards the new phone and made me choose the monthly installments at whatever it is, 51 dollars a month or something like that. So, I chose that since it was a launch day date (last Friday) and said i will deal with it later thinking no problem. Well after talking to 6 different people and an ATT store visit, they said that there was nothing that they could do until the preorders showed up in their sales system which would have likely been middle of last week based on who I talked to, and they couldn't guarantee that they would be able to keep my order. They said that there was a good possibilty that they would have to cancel my order and create a new one and therefore forefeiting my launch day date. So, I think I will stick to the apple app and deal with the wait time. So, needless to say, I am not happy with the way ATT handled the situation and how I got bounced around so many times.
So, I am not sure what role the sales system plays in pre-orders, but judging by the "middle of next week" comment I got when I talked to someone in the sales department on Oct 27th, that could be why we haven't seen any movement yet.
