The N9, made from a unibody plastic shell, filled with internals, then sealed off with a curved gorilla glass screen.

Two things,
Is it safe to say, that if nokia hasn't mentioned as yet, it isn't waterproof?
How hard would it be to waterproof it?

Another feature i cannot understand being excluded, it has almost no moving parts, in a unibody chassis! waterproofing it would be a simple task.

thoughts?
