Yeah I know. You're freaking out. RELAX.
Your phone will ship on time. Verizon fulfills orders based on location and type of phone. They won't be shipping you a phone from 3000 miles away. A fulfillment center within 1-2 day shipping will fulfill your order. This center just hasn't gotten to your order yet.
A worker has to go to each order and fulfill it. So the workers will open a box of phones and fulfill them. They have a phone for you if you have a 9/19 date.
2 years ago I had the same concerns as you. But 1 day before release they finally posted my order under order history, got receipt and tracking. My brother who ordered 2 hrs after me got his tracking 2 days earlier. I was freaking as I didn't even have CC charge when his shipped. The difference in our orders was mine was the larger 64GB phone and he had 32.
I'll tell everyone 1 more time... RELAX!!
Wow they are now shipping the larger 128 phones. Shocking
If only people would just relax.
