Ordered 256GB silver AT&T, got in pretty quick after go-live, initial screen showed Nov 3 delivery. Everything went smooth, chose Apple Pay as my payment option, it wouldn't take...said the phone wasn't near and/or BT wasn't on (nether were true.) Tried a 2nd time, got the  same message, had to resort to normal payment methods...by the time I got it paid, delivery was Nov 10-17. Already got my confirmation email as well. Grrrr! Was even on a Mac and using Safari, all Apple ecosystem, and it failed me!
Oh well, Im guessing I'll move up in the list as things start shipping, and still pretty happy with even a mid-November date, considering all the doom and gloom being disced regarding short supplies.
ON another note, tried to order a 2nd one and was told I could only do that once I received and activated my current phone!
