One of the cool new features that was added to Android with the official debut of Gingerbread yesterday was the new keyboard. If you want that new keyboard and have an Android 2.2 device that has been rooted, you can install it right now.
What you have to do is follow a few steps to get the deed done. You have to grab a zip file that is flashed to the smartphone just like any other ROM or software. You will then need to reboot and select the Android keyboard option under input method and you are ready to use the new keyboard.
The directions are on Droid-Life and should work with all rooted 2.2 devices. If you have been looking for a compelling reason to root your device, this may be it.
