I was looking for a N9 as a bithday-present for a friend.
Now I collected some more money from other friends and just bought a new black 16GB for 219€ on german ebay. There I also found this unicorn 16GB N9: http://www.ebay.de/itm/151026779646.
From email I know the seller is known here as explit. Sadly he cannot provide the original receipt.
Actually it's at 79€, auction ends in 2,5 hours.
So for everybody interested: be quick and not too cheap.

PS: I have no relation to the seller and I don't know him personally.
Just thought I point to this unicorn because he doesn't.
