I ordered my iPad the day preorders began, and my order status is "Shipped." I checked my online banking after the purchase to make sure they charged my card, and it showed up under "pending transactions." Now, it shows nothing. No trace of a transaction in my bank account. I have a shipping number, and it appears to already be in Pennsylvania. Should I be worried? Could they potentially cancel my order? Will they recharge me once I receive it? I clicked "cancel order" just to see what would happen, and it said that I cannot cancel the order because it has already shipped. Should I call Apple? What's going on here?!
