I also believe most Jet Black 128GB 7Plus with as late as Oct13-20 shipping dates ordered before 12:10 PDT or so will arrive on Friday as well if previous year precedent follows. In 2014 the Gold 64bit 6Plus (or any 6Plus for that matter) was the hot item.. I only remember a few reports, back in the PreOrder thread that year, where they didn't get their 6Plus on launch day after having had distant shipping dates.. Then same thing with the hot RoseGold 64bit 6SPlus last year.. October shipping dates - almost all came launch day. So in 2014 with 1-week turnaround til launch day or last year with 2-week turnaround.. same result..
You see - AT&T actually NEVER has ANY stock of the most popular anticipated iPhone in a given year. Apple holds it back on purpose to control supply. This is why NO ONE got a 9/16 ship date for JetBlack 128GB 7+ on PreOrder night. It's because AT&T has ZERO units in stock as of pre order night. ZERO!

..
This week Apple will start releasing stock to Carriers.. And that's when you'll start seeing your ship dates change. Last year we didn't see ship dates start changing until Wednesday or Thursday of launch week. And with no rhyme or reason to the time stamp on your order. People who ordered rose gold 64 Plus at 1 hour after pre order went live got their shipping dates moved up prior to people who ordered at 7 minutes before scheduled live opening on pre order night.. But ALL (but a few) got their RoseGold 64GB 6SPlus' on launch day..
So as I've been saying for the last two years… Breathe… if you pre-ordered within the first 30 minutes of AT&T app or online store going live… your JetBlack 128GB 7Plus will be there on launch day. ;-) Apple's not going to send AT&T "zero" units.
