Data Points
I placed my order with att.com at 5:15 a.m. EDT on the 15th (having despaired after 75 minutes of ever getting through the Apple website), got an order confirmation on the 16th (listing the 16th as the order date), received the CSS email this morning around 10:30 am, and just received a UPS tracking number with a ship date of June 21--which was good, since I first checked the Apple Store and discovered with initial horror that my Apple order, placed around 7 pm on the 15th (when I was despairing of AT&T ever acknowledging my order) was just cancelled. It looks as if AT&T and Apple did get their systems to finally talk to one another since the Apple cancellation and the AT&T tracking number assignment were near simultaneous. (And like others, I received no warning or explanatory email from Apple--not that I needed one after I nervously checked order status on AT&T.)
I'm really getting much too old for this.
Good luck to us all!
