Q: I have an iPhone which I sync with iTunes 9. I am getting an iPod classic to store all my music on.
Can I sync both devices with iTunes on the same PC?
A: Absolutely. There is no real limit to how many iPod or iPhone (or even Apple TV) devices can be connected to the same iTunes library, and you can even connect and sync them all at the same time if you have enough USB ports available.
To set it up, just plug it in. Each device that you connect to your iTunes library gets its own configuration and synchronization settings in iTunes, so you can easily sync different types of content and different playlists to each device, or even sync some devices automatically and manage others manually.
