I was late ordering my 6 64gb gold (1:30pm on 9/13) and have been seeing my status changing from processed to preparing to ship back to pending all week. This morning I checked through Premiers website at about 9am-it was pending and the cancel button was back. I walked past the huge lines at apple and AT&T and ALMOST queued up to wait, but checked ONE MORE TIME through the myatt app, and I had a tracking number through FedEx. Left Fort Worth this morning.
AT&Ts website still says pending with ship dates of 9/23-10/2, the option to cancel is still there, and my card has NOT been charged yet. So even though it's not coming on launch day, it IS coming, and the only reason I know is the app.
FWIW, I also tried to track using reference AFTER finding my order with the tracking number and it doesn't come up-the reference number is completely different from my order number and my phone number.
I've felt so much better all week reading posts here and knowing I wasn't alone in feeling left in the dark about if I was even getting a phone, I hope that helps some who are still frustrated with the complete lack of info about their shipments. I'm still waiting on a shipped text or email from att or fedex, just because they haven't sent anything doesn't mean that your new phone isn't on it's way already!
TL;DR: iphone 6 64gb is in transit despite no notifications or communication from att or fedex, and no cc charges. Myatt app seems to be most accurate source of info.
