I've been following this thread for half my life now, so in case this helps anyone else, I thought I'd post my tracking info in full.
Details - I pre-ordered one i6+ in space grey at around 6am ET on 9/12, and got a delivery estimate of Oct 1-6. That changed to processing on 9/18, and then shipped on 9/19. According to UPS tracking, I was originally scheduled to receive my phone on 9/22 (early) or 9/23 (regular delivery). Mine came Worldwide Express Saver. I never contacted Apple or UPS about my order or delivery.
My phone is out for delivery now, and I have my fingers crossed it will make it - any delay now would be purely local, since there's a bit of road construction on my street today.
