My Gf is still running 2.0 and she thinks her phone will blow up or something if I update her software. Meanwhile, her phone is so buggy it doesn't work half the time. I'm trying to convince her to let me update her phone and, since she doesn't have a computer, give her access to itunes so she can manage her music. I'm running Leopard on my iMac. If creating a new user for her will that allow her to manage all her music, run software updates, etc on my computer? (She did sync to a friend's PC when she got her phone, but hasn't plugged it into a computer since. She's been considering getting a notebook, but the only thing she would use it for would be to manage music in itunes. Seems like a waste of money, especially if this would work). Will this work? Can you have two music libraries and two phones sync to one mac?
