Updated AT&T Status
Totally agree that the Apple Store POS has proven more reliable in past iPhone purchases (esp. at initial launch). I wasn't able to order my (2 x 6 Plus, 128GB, Gold phones) until after 9am EST on 9/12, and initially the ship date was between 11/3-11/27 in a "Preparing to ship" status.
As of this afternoon (9/14, 3pm EST), the ship date changed to 10/31-11/11. I expected this to occur since many "cats" cancelled their AT&T orders and as the system updates, the dates become more solidified. What's interesting to me though is that the very first post to this thread, the user said he purchased within the first 27 mins, and he has the same ship date (10/31-11/11). Again, just interesting. I'm optimistic that the phones will ship by this date or perhaps earlier. I've played this game many times before and even though the dates change or the status says "backordered", all of a sudden on the day prior the phones are available at the store, the status pops and the tracking number is available.
