Looks like AT&T and Apple can’t even take all the customers they want, with some customers reporting their pre-orders have been cancelled:
Your iPhone order has been cancelled. Your credit card has not been charged. If you believe you have received this email in error, please return to the AT&T store where you placed your order. Sincerely, AT&T
It’s probably a good idea to wait if you want the iPhone 4, especially with the number of things that have gone south including exposure of customer’s personal information during the pre-orders.
And all of this, of course, coming from a company that can’t do a single thing right including dropping calls like they aren’t a real cellular company that wants to deal with customers the “right” way.
Until AT&T figures out how to deal with orders (and actually be able to take them instead of cancelling them), it might be a wise advice to stay put. Better yet, you might actually want to hear what Verizon is coming out with in 2 days with the new Droid X, supposedly the new king of smartphones.
