Following up on Zune hacks such as how to use the Zune as a portable hard drive, how to share songs multiple times, and how to bypass the Wi-Fi sharing DRM, there's now a hack to sync your Zune with any PC.

Technically, you could sync your Zune with any PC before, but gave you a pesky "guest" mode where you couldn't do as much as you could if it were the "main" Zune for that library. By installing this hack, you trick the software into thinking that every Zune is the Zune it's married to (someone needs to get on this hack for Catherine Zeta Jones), and thus get full syncing.
