I've yet to find an answer to this. When I went through the reservation process for in-store pickup, I never logged into the Apple page. I was never asked to and didn't even consider it (yes, I'm an idiot). Now I'm super worried. I gave Apple the information they asked for, such as my phone number and the last four of my social, and through that they were able to pull up my correct AT&T Plan, but should I be worried? I should also note that since I never entered an email address, I never got a confirmation email.
