We put so much stock into negative emails yet nothing into credible evidence to the contrary.
At any rate, here's a good example of why you can't rely on ATTs word 100%. Look at this found in the premiere email confirmation I reviewed about 1.5 hours after I ordered my phone:
"For preorders, charges will be processed on date of shipping and will include actual, applicable taxes, fees, and surcharges, which may vary from the quoted estimate."
One of my phones shipped yesterday and there's not a single charge on my account so we know that's not entirely accurate. It's plausible many will still review their phones tomorrow in spite of what an email or order status page says.
