I had the same problem,on 12am on the 15th when the pre-orders started i started trying to order,i kept trying over and over on Apple....nothing,finally at 4:58am central time ATT's site came back up after being down for maintenance so i ordered and it went through,i got an order # but never received an email confirmation or a cc charge so i was concerned it didn't go through so i spent most of the day on and off the ph with ATT,they could find no record of my order one rep said it probably went through while 3 others said it probabbly didn't so me be concerned it didn't go through decided to try Apple 1 more time at around 9:30pm c time,7:30 p time i got an order to go through and got a confirmation email about 5 hrs later for a delivery date of the 24th.Then what do you know? the next morning i get an email from ATT saying my order couldn't be verified because cc charge wouldn't go through could i please call with updated payment info so they could process my order,my cc company blocked it as they saw 2 different charges coming in for the same amount and thought it might be fraudulent,so i called ATT and told them to cancel the order that i had already ordered another through Apple as they told me my order probably hadn't gone through.Believe me the last few days have been exhausting,first being up from 12am to 6am on the 15th then on and off the ph all day most the time on hold trying to find out about my order,then trying to get through yesterday,4 or 5 times i waited on hold for 20 to 30min only to have someone come on and tell me to call back later because of high call volume finally i got through around 9pm so i was ably to cancel the ATT order,talk about a long 2 days but at least i got my Apple order and i'll have it on the 24th! If i were you i'd cancel the ATT order,if they both try to run through they might both cancel the orders and then you' be without an order at all,better to be safe then sorry
