I ordered a 6/64gb/gold(wife's) and 6+/64gb/sg(mine) within 10-15 after "official" launch time on AT&T (about 3:10am). Didn't get confirmation emails until about 4:30am est. wife's has always said 9/17-18. I got the 14-21 days and stated with 10/13-22, this changed to 10/2-13 during the weekend. Got my wife's tracking today but my 6+ Still shows preparing to ship. I say all that to say this (haha), my wife's tracking shows it started on 9/13 and when I check her upgrade status it says she will be eligible on 4/13/16. When I check mine, I also show 4/13/16. Any chance this means something? Hoping mine just hasn't updated yet.
I have been reading through this thread for a couple of says. I apologize if I am rehashing this.
