^^ Did you see the date of the post you linked above ? It is of 2008. That time a photoshopped image of a Nokia concept phone emerged on the web.
Does the phone purchased by your friend looks like that one or is it like this:
YouTube - NEW NOKIA N98
Doesn't matter anyways. Because the concept phone never became a reality.
And one more thing, Nokia phones have changed thier model nomenclature. So any new phone from Nokia would have a single digit as its model no. & not two digits. eg: n8, n9 , x6, etc.
