I ordered the same phone for AT&T via Apples website at 7:50AM EST 9/20 and my order is still processing.
I really have no idea why I was fortunate enough to get mine so early. I thought everyone else would as well. Forever it said "Processing Order" or something else, with just the expected arrival date of 10/21-10/28. I was OK with that because I knew there were people ordering at 3 am on 9/20.
When I noticed the change in status early last week, I was of course happy. But again, I thought they put the later month dates to keep everyone's expectations at bay. And again, I'm not sure why my order was shipped via FedEx vs. UPS. (I DO hate UPS BTW)
