I'm on a family plan and I'm iPhone upgrade eligible- can I go to AT&T and activate my new iPhone without having to take one of my parents- since I'm not adding a new line and I plan on paying for the phone myself anyway?
By buying the 3g you will be changing the contract since you're adding another 2 years. My guess would be that you would need one of your parents, or maybe just the last 4 digits of their ss#.
