I wouldn't be too sure. You're on your way from AK to KY. Some of us (myself included) have been in KY since sunday and are still expecting 10/2 delivery. Its not that their backed up, its that they are holding shipments by request of Apple so as not to exceed the original delivery dates.
I figure nobody here knows the answer to this...but why would they hold a shipment now to match the estimated delivery date? Its not as though this is the first release date for the phones. UPS has never bothered to hold shipments before for me, if they can deliver them early and there's no special release date to hold for.
This is a poor way to do business for both Apple and UPS. Seems like they could have done it so much differently and had a whole lot of people happy with getting their phones before projected dates. Now I MAY get it before one of the projected dates, but I'm irritated and ranting here because nothing makes sense in all this.
Sorry for the rant...
