I have purchased the new iPhone on release day everyday since the first launch. This year my line has been transferred to the company that I work for. My plan is to pay full price for the 5 (selling my 4s to recoup some of th cost). My question is: since the 5 doesn't have the same SIM as the 4s I can't just swap them when the new phone arrives, I'll have to activate it in iTunes. Since it's been a long time I can't remember if you need account details to do this. I clearly don't know the social or the billing info for the company. Anyone done something like this in a past launch that can lend some insight? I would like to not have to tell the company anything if I can, since I own my current phone and am paying for the new one.
