I was torn between the green and white and the one I purchased, I owned a black N9 at time of ordering otherwise I would have for sure gone for teh green/white, would have made a lovely match for a white N9.

I'm pretty sure that ebay seller is genuine, the official seller I linked to was also based in Hong Kong so no need to read into that to be honest. It's the only person selling them on ebay and if they were fakes I'm sure there would be more of them, even the price matches the official resellers price.

Actually I wouldn't be one bit surprised if it's the same base, now I think of it I remember sending both the seller I linked to, and that seller on ebay a question prior to ordering, and had the exact same response from both.
