Been trying to figure this out and seem to be keep getting lost in how to do it. I have an iPhone that I want to be able to access and sync with my iTunes account on two computers. I currently have iTunes on both computers but they don't have the same songs and apps on them. I use my Desktop as my main computer for iTunes and my Laptop when I am in other rooms of my house. There are times when I find a new song or app on iTunes with my laptop and download it but if I sync my iPhone then I lose songs and apps because they weren't on the laptop but were on the Desktop. How can I sync my iPhone with my Laptop when I buy a song or app and not lose everything in it that was set up from my Desktop iTunes?
