If you just nabbed a Nexus One either through Google’s developer dashboard or some other means, you may still be interested in rooting it. Although rooting the Nexus One is a lot easier than most other Android handsets to date, there’s just something about the ease of a one-click solution that makes rooting it a worry-free process.
The exploit it uses to root the device is the same exploit that was used to root the Motorola Droid X (using UniversalAndroot). UniversalAndroot actually support several other devices with the Nexus One being the latest added into the mix. The app comes with built-in unroot functionality, as well, and will also help you install custom ROMs. The best part? It’s free to download. Head on over to XDA to get started.
