I just called and had my iPhone held and the automated system says they hold it for 5 business days from the date of available for pickup.
oh great that means my watch will be returned to best buy and will have to be reshipped after they potentially allocate it for someone else. I knew this was going to cause a logistics nightmare. I guess I just gotta cross my fingers and pray that my local apple store will have some sort of stock come the 16th.
