I think it is time to reveal its final price. The minimum price that I would accept is 500 euro. A few days ago, a "common" black N950 16GB in similar condition with this one was sold for more than 400 euro. This one I have here is the factory unreleased prototype silver version of 64GB storage, and is fully functional, so I will not accept any offer lower than 500 euro. I will consider though trading with another device that might interest me, you can send me your offers regarding exchange.
