Anybody stuck in the "processing" state right now that ordered in a timely fashion have simply not had a phone assigned to them yet, and this will be completed by September 19th @ 2200 EST.
I like how someone pointed out you originally typed September 17th, but now you changed it to the 19th. I've seen multiple screenshots of people who bought 16GB white phones shipping from Illinois, while all the shipping screenshots I've seen from people who bought the 16GB black phone have been coming from Nashville. Sadly, mine can't be found on UPS' website yet.
