Hey guys, I just realized that I used the wrong credit card when buying my new iPad. Do any of you guys know if I can call them up to change what credit card I have bought it on? The online system will not let me. I know the lines are really busy right now so there's no chance I can get through now. I don't want to have to cancel and reorder later, especially since it will likely mean that I will not get it on launch day. Does anyone have any experience with this?
