Ahmed, I refer you to this thread, where it was proved incontravertibly that n900 is for girls. Indeed, as a result of that thread the n900 mirror app was created. (Though I think the devs wussed out of trying to make a fertility monitor because of the 'ick' factor in some of the indices )

I'm still waiting for the weather to improve so I can carry the n900 where I always promised I would.
