So those who ordered from ATT at the moment orders went live still didn't get a ship estimate before 9/23 -9/30? That is what I got ordering black 128gb 7 plus at about 1pm ET on Friday after all kinds of complications in their system, and just assumed people beat me to it by ordering earlier for delivery on release date. That makes me feel somewhat optimistic that maybe it will be at the earlier part of that time frame than later (or maybe even they are being cautious and it may come even before)?
Unfortunately, my past experience with a 6 order at launch through ATT was horrific, it ended up arriving nearly 2 weeks after a similar estimate, supposed to be delivered about a week after launch but got bumped a few times 'on backorder' and made it eventually after 3 weeks.
But with the 6s Plus, decided instead to just search around for one as soon as they went live at retail, but that too 3 weeks as well to track one down at an Apple store.
Here is hoping.
