Where did you guys with 'NOKNA' on your box get your phones from?

I've just bought one new on Ebay from U.S. and it says 'N900_NOKNA_BLK' above the barcode on the white sticker on the box.

Do you guys think this is fake? If there are those with similar stickers bought from retail stores, I'd be a bit more confident that this is not fake...
