Submitted order at 12.01. The option to purchase was loaded earlier. The weird thing was that it asked me if i want to include a Sim card and when i said yes, it forced me to buy a global data plan. I hope I will be able to cancel it when I get the phone. I didn't want to get the phone without a sim card.
Same thing happened to me on Verizon. Just called Verizon and confirmed that yes, we can cancel the global data plan. It will probably show up in our accounts once we activate the iPhone 4S, but we can call and have it removed. It was confusing!
