Back when the 4S was released, my upgrade date was 3 weeks after the launch. I knew this when the event was happening, but when I checked (just to do it) eligibility when orders were available, the date had changed. Not sure if this was random or not, but it happened. My upgrade date is Sept 21st, and by then the 6S will be backordered like crazy. Have any of you who are AT&T customers had any success in the past with having them move the date back a couple of weeks? I have a feeling they're just going to say "you ARE eligible....for AT&T Next". Not what I want to hear. Anyway, just getting some feedback before I call later. Am I wasting my time calling? Can they even do that?
