I think you would find it would be very hard to obtain a genuine N900 let alone a brand new N900. As you would have already known nokia no longer produces them and if you're lucky enough to find them selling in the shops it might be second hand.

Hong Kong is fairly well-known notorious place to sell second hand items that are dubbed as new. Before there was a thread about N900 scammers be aware thread I bought my second N900 from there which the shop owner convinced me it was brand new. Truth be told that it seems the previous owner did not bother to reflash the device completely let alone restoring to defaults.
