I preordered my iPhone 6s Plus in space gray. I was given an estimated delivery date of 10/7. I haven't ever preordered through Verizon before. Therefore, I was wondering how accurate that was. Is that a pretty set date. Or, are they similar to Apple in that they give you a later date just to play it safe and there is a strong chance I could get the phone earlier that the estimated date. Thanks for any help .
