So I pre ordered three iphones for the family. My wife will use my iTunes because she really doesn't care to know how things work. The third is for my daughter who is away at school. If I activate her phone on my iTunes, is it then tied to my iTunes? I want her to have it set up for her iTunes up at school, but don't want her to have to accept any liability. I am probably over thinking this, but am clueless and also trying to avoid accompanying my wife for the phone delivery ride this weekend.
