What do I need, and what do I need to know? I am on a family plan so do I need my Dad's SSN? Can I upgrade my phone without the account holder present? What about pre-ordering, if I preorder it with the SSN will I need him present? I have my own account on AT&T's website for my phone even though its part of a family plan, if I upgrade through them can I avoid that issue. I'm in college so I don't know if going with my dad to the apple store is an option.
