Mine originally said it had to be manually entered, then on Saturday they emailed me giving me a new order number ("In order to complete your request it was necessary to assign a new order number.")
The new number now just says Your order is being processed. If you have any questions, please contact a representative at your original point of purchase.
It does say it was updated as of 10/10, so guessing something is happening.
Received the same email Sun morning. Order was cancelled then reassigned a new order number. New status shows just that the order is processing. I ordered a 64GB model which still shows as being able to preorder for the 14th, so I would assume that the order number cancel/change won't affect my getting it on the 14th/15th.
Only other thing of interest is that I'm porting my number from AT&T(new account with Sprint). That second email stated that the porting had been submitted and that the number would be ported by the end of Oct. My assumption is that it is the window for the porting to be completed in. I hope that the porting of numbers doesn't back up my order.
