Yes it very disappointing... I'm completely upset with Apple! If they didn't have the phones in stock or ready don't sell them yet. The could of easily said Jet Black alavible in October if they didn't have the iPhones ready. This kinda stuff that Apple has done makes me rather want to get a "Non explosive" Galaxy Note 7 version and call it a day!
I agree, same with Matte black in the Plus in the larger 2 capacities. Why allow people to preorder without some disclaimer like "will not be available until after launch) if you had none! The whole point of a 12PST3am EST is to PRE-ORDER a phone to get is the 16th. Regardless of the estimated dates, those have been proven in the past to be WAY overestimated and not reliable to begin with.
It is just frustrating and borderline false advertising if they had zero for launch.
