Hello, So I'm finally going to take the plunge and get the black iP4. However, I wanted to do so without renewing my family's contract. My grandma is actually on our family plan, and could care less about her upgrade that she has had for a year now. My question is...how can I use her upgrade for myself, without messing up her number or anything? Can I simply go to Apple.com, put in her phone number and then apple ships me the unactivated phone and I can then just activate it myself for my number? Any help would be appreciated! Thanks!
