Google has yet to officially release Android 2.3 Gingerbread for the Google Nexus One smartphone, but some folks at the xda-developers forum have already managed to get Android 3.0 Honeycomb up and running on Google’s developer phone.
Actually, running might be a strong word for it, because while the basic operating system is working in this early release, phone calls, SMS, and other phone functionality isn’t yet available. 3D performance is also pretty sluggish.
The version of Honeycomb used comes from the emulator image released as part of Google’s software developer kit for Android 3.0. It’s still a bit rough around the edges and because the Honeycomb source code hasn’t been fully released yet, there’s still a lot of room for to grow. But xda-developers forum member bypass23 has pre-rooted the disk image, added busybox, a file manager, QuickBoot reboot options, and a terminal emulator.
You can find a download link and more information at the xda-developers forum.
