Does anyone have an answer to this yet?
Just spoke with AT&T... Firstly, the $40 data charge does not take into account the $25 discount for having the mobile share (10gb) plan. So the charge is accurate (it will show the discount on your bill).
Secondly, they had trouble finding my preorder for one of my lines. The manager got involved and basically the answer was that they won't have complete & accurate information in their internal systems for the preorders until tomorrow (24 hours later). It's kinda crazy, but I guess it's not completely surprising with the insane volume of orders coming in.
