My girlfriend is up for the discounted upgrade and wants to give it to me. What is the best way to go about it? AT&T, Apple Store, Apple online store? If I buy it online and they send it on the 19th, does it have to be activated under her name, or can I just activate it myself? If it has to be under her name initially, I should be able to switch it to mine whenever I want right? Thank You for the time in answering.
