As mentioned, I have a later "contract end date" (Nov 11th), but the customer service rep for Verizon said all 3 of my lines have an "early upgrade option", despite my contract end date being in early Nov.
For me, the question is (and VZ customer support on Twitter wasn't sure), will my "early upgrade option" be "available" at 12:01am PST when the pre-orders open up.
