So I'm in a dilema. My wife's computer got a virus and will no longer turn on. This was the computer that her iphone 4 was synced to. So we are now wondering if she plugs her phone into my laptop, a) will she lose all her music b) will she lose her apps. c) is there a way for her to log in to her account on itunes and all her music be there. She doesnt want to lose her music or apps but wants to be able to back up and update software.
