Was Dexter Using A Prototype N8?

Okay, so before anyone shoots me I know these Dexter episodes are super old; but I've only just started watching it so cut me some slack- regardless everyone knows that Dexter is a huge fan of Nokias first using the E71/73 then the N82 and of course the N8. What drew my attention though is that instead of the N8 branding in the upper left corner it says "C0"which is Nokia code-speak for unlaunched protoype devices; now the original air date of this episode (S5 E7) is November 7th, although it's after the launch of the N8 these episodes are obviously filmed weeks or even months before.

Although this is completely unimportant or irrelevant just thought it was a nice spot.
