iTunes doesn’t like you to sync your iDevice with more than one computer. When you try, it tells you that you’ve already synced it with another library, and it wants to erase your device!
But, what if you don’t want to erase your device and no longer have access to your old iTunes library? What if you want to sync your iDevice to whatever computer you want?
