Everyone Check your fed-ex tracking numbers! If you have a surprising delivery date of 9/18 on Fed-Ex's site, it will soon change to 9/19.
The reason:
The phones are leaving the Verizon, AT&T Distribution centers as they are fulfilled and handed over to Fed-ex. They will then be put on "HOLD" at a secure Fed-ex warehouse for the rest of the week, and will be released Wednesday or Thursday night (based on your distance from Fed-ex hubs) to just make delivery on 9/19. Apple and the Carriers has paid big bucks to not let them loose before then. But rest be assured a few phones will accidentally get past this "hold" pattern. But the majority will be coming on the 19th.
For those without a tracking number yet, be patient. As the respective distribution center processes your order, it is added to that "hold facility shipment" for that day. So some of you may not see your number come up until mid-week. As long as you were given a delivery date of 9/19, barring you have no order changes or credit card issues, you will get the phone on time.
