If you are a Nokia N900 user and also want to run Android 2.3 aka Gingerbread in the N900, there is a great news today that a hacker team named as NITDroid has been successfully hacked the N900 to be able to run Android Gingerbread.
Currently not everything is fully functional. Only cellular data, sound, Wifi and various other things are working fine. They are doing more to make it stable by the end of this year.
Great job NITDroid.
