I am getting a new iMac i3 today! Pumped. I have my iTunes library set up exactly how I like it; it's beautiful. I have my 3GS synced to that account. My wife has her iPhone synced to her old PC that is still at her parent's house. She doesn't care about software updates, backing up the phone, or apps. To her, it's just a phone. On the other hand, I need all of MY data and info to be perfectly intact. Can I allow her to somehow sync on the new computer with her iPhone without causing any problems? What is the simplest way to have two different iPhones with different songs and apps, synced to one computer.
