Recently a friend of mine told me about an attempt to put Android 4.0 on Samsung GT540, it seemed too unrealistic but it is perfectly true, here is the link to the blog of the person who is attempting such a feat.

And to give a special touch, a video too.

If someone wants to try, do not forget to leave some feedback about this experience :)
