Authorized Retailers order just like us but on a different format. At midnight they also had to bum rush their servers, different than public of course. So they don't get an automatic stock of phones.
AT&T Company Stores however get a set amount from AT&T. Each store is different obviously based on location/traffic/etc.
A friend of mine owns an AT&T store in the area, and he told me, today, that he received 5 phones total: 2 64GB Gold iPhone 6 and 3 16GB Gold iPhone 6.
Zero iPhone 6 Plus.
His store is an official AT&T retailer.
Meanwhile, does he know what he will get later today, or on Friday?
Doubt it.
