Can I buy an iPhone at the apple store without my parent?

I plan on camping out at the apple store next week with a friend to get the new iPhone 5S. I'm 17. We currently have a family plan with AT&T. What are the processes when buying an iPhone from Apple? Am I going to need my parent with me when I purchase the phone? Or do they just check if you are upgrade eligible and send you on your way so you can activate the phone when you get home?

You are buying a phone which would be on a contract. You can't buy one on your own until you are 18+.

You have to be 18 to enter into a contract.

You can buy it outright, but to add it to the family share plan as an upgrade for the 199 price your parents will need to be there, or at least the one that has the account in their name.

You can go and pay the retail price but to add it to your family plan, the primary person must be there and you are not old enough to sign a contract anyway.

Unfortunately No. Its the same with most phones now even though I don't really understand it my self. You have to have some form of ID like a Proof Of Age Card, Birth Certificate, Medicare Card or License, I also think a Bank Card is included as well. Otherwise if you have none of those you need an adult to be there with you. But if you do have most of the ID cards then you could probably do it. If you are going for a plan though A Proof Of Age Card is most Important of the lot.
