My husband and I both have iphones, I have the 3gs and he has the 4g..... when he plugged in his iphone to itunes for the first time, he pressed the worng button and suddenly, both phones are called "home phone" and we keep trading info instead of having two seperate profiles. So I ask - is there a way to go back and set up a different profile for him so he doesn't get my songs and apps (which he doesn't want)
