I am trying to get the iPhone 5S on my girlfriends account. She gave me the go ahead and added me as an authorized user on her account. I bought a 5 last year and gave it to her, so she was willing to hold off on the upgrade this year and will use mine next year. My question is, will this be difficult and will she be required to be with me as i'm an Authorized User on her account? I intend to attempt to try at 3am to buy it and have it available for in store pick up, if it isn't possible I will go stand in line somewhere. Will I run into any snags? Has anyone done something like this before? I'd love to know your experience and any tips.
