I think I already know the answer to this but... here's my problem. I'm not 18 yet, and my line (on a family plan) is eligible for the $199/299 iPhone. I was planning on taking advantage of that. My original plan was to wait in line at the Apple Store on launch day. Can I do that if I'm not 18 and am taking advantage of the subsidized price but am the owner of my line? If not, will the AT&T store be any different? And if not that, can I preorder it online and pick it up on launch day? What are my options here? Do you even have to be 18 to renew it like I'm planning?
