Can/how do I update his iPhone on the family's Windows tower PC? Do I just plug it into the tower like he normally does (which he knows how to do) and it just checks for things on it's own. He has windows 7 if that means anything helpful. I don't want to plug his iPhone into my MBP because he's had it hooked up to the windows tower. (I don't want to inadvertently damage my MBP.) Thank you!
