This happened to me. Placing my gold 5S order just short of 4 minutes after the online release I had an immediate shipping date of between the 11-16 of October. This was shortly pushed back to the 16-24, where I was going to simply cancel my order and hope to buy instore. Me never being lucky it turned out that my phone changed from processing to preparing to ship, then shipped in as little as 24 hrs. My 16-24 ship date turned into having my phone delivered by October 2 by the end of the day.I'd be much more aggravated if I had ordered as early as you and was still iphone-less.
For what it's worth it seems like folks are getting expedited shipping for back ordered phones. So maybe you will see that sooner than you think.
I am really losing my patience. It isn't that I'm a prima donna, I just hate situations where there is no recourse.
For those still on processing hang in there. Things can change real quick.
