My mom just got an iphone 4 on verizon. She wanted decided to load itunes onto her work computer and used her work email address for it. She has a macbook with her music on it at home with her personal email address. Is there any way to get that music on her phone? She bought a GPS app and it requires her to plug it in which she can't because she isn't at work. She is afraid if she syncs at home that she can't backup the app to itunes on her work computer. Make sense?
