Sorry, but Apple's thumb-keyboard is WAY easier to use than Nokia's default. It's smaller, yes, but much more responsive and accurate anyway. Have you tries the Enlightenment demo of the Apple keyboard on the IT? It is awesome. (A few people have begun using it in their maemo apps.)

Anyway, I think it would serve Nokia well to look at the Apple UIs -- as they probably already do -- and vice versa.
