Basically, my old man has a Cingular family plan dealie, and iv'e currently got a RAZR. I want to get an iPhone. I plan to camp out for one. My father will not be joining my camping adventure. Will I be able to purchase the iPhone and take it home for him to activate or whatever? Or will they require all that to be done right there in the store? My credit is pretty bad so I don't think I can sign up on my own?
