As per usual, the Verizon website was not ready for prime time at the stroke of 12:01 Pacific. By the time it actually refreshed with the option to upgrade to an iPhone 7+, the earliest date was already pushed to 9/23. Mine is an Apple Black 256 GB.
Wish I could have used Apple's site but I'm using Verizon's upgrade program, so I had to go through their molasses field.
Bummed I won't be joining in the fun on day 1, but I'm still geeked to start snapping photos with this beauty on the 23rd.
My experience was identical to yours. Did it keep going to the "Get emails about preordering" page instead of the order page? That was so annoying.
