I am looking to order the black 64gb X when it becomes available to order on the 27th. I will want to sign up for the apple upgrade program when I place my order and considering the expected shortage in stock I was going to ask if any of you have experience with an online signup for the upgrade program during a new product launch and if there are any tips to speed up the enrollment process so that I can submit the request quickly before shipping times start to slip. Any info is appreciated.
