Email from Apple cancels iPhone 4 pre-order

There’s something strange, in the neighborhood, who you’re gonna call? Definitely not the Ghostbusters but a lawyer, especially when you receive an email from Apple as follows.

Dear Customer, we were unable to complete the authorization process for your iPhone order. As a result, we had to cancel your iPhone order. To complete the purchase of your iPhone, please visit an Apple Retail Store or an AT&T company owned retail store. We apologize for this inconvenience.

Does this have to do with the recent system slip up by AT, or does it have more to do with a shortage of displays for the iPhone 4? All we know is, there are plenty of frustrated folks out there who wish that they had better fortune with their pre-orders.
