So i am ordering an iPhone for my dad and I with his credit card tonight. I forgot what I did last time. As long as his card is in my iTunes i should be fine right? The shipping address is different than billing but it does not work the way it used to right? Also i will be ordering the t mobile unlocked phone. Or do i need to order gift cards and use those? If so what are the taxes on the 128 and 256 jet black with apple care.
