My CC now shows a pending charge from Apple for the 7+ matte black 128gb. Status of the order has changed to "Preparing for Shipment"; going to Delaware. Still shows the Oct 4-10 estimated delivery date, but I now think it will ship within a week.
I too had the joy of not being able to order until 12:12am PST, even though I was punching the enter key or iPhone screen at exactly 12:00:01am. The apple store app on two iPhones and the Apple web store would not work until then.
Was actually on the fence about cancelling the order. My iPhone 6+ runs fine and never runs out of battery; skipped the 6S+ as there wasn't any real reason to upgrade, imo. Now the 7+ is out and frankly I don't see a compelling reason to shell out $800, other than my son just cracked his old Note 3 screen, so rather than fix that I'll give him my 6+.
I can no longer cancel the order, so that settles that.
