That means harmattan is most likely not installed on the device. At least it's not exactly the same thing as the one you know. I think no one here can tell you what the exact differences are. If you're lucky they only changed the name at that point, because it's supposedly made directly after the n9.

This does not mean that it's theoretically impossible to install harmattan. Nor does it mean that it's possible. (Not much help, I know.)
