If you are in the Netherlands or Belgium however you can now purchase the Lumia 950 or 950 XL for delivery tomorrow, unlocked.
Belsimpel.nl are listing the devices as in stock and ready for Next Day Delivery. In case this is an error I have spoken by telephone to their customer service department who have confirmed the devices are indeed on sale, and that they have already sold a few.
Unfortunately they are only shipping in the Netherlands or Belgium, but if you are lucky enough to be in one of those areas and intend to purchase the device we suggest you grab it directly, before Microsoft slams the doors shut.
Update: It seems it was too good to be true, as Belsimpel is now telling buyers delivery will be in 4-6 weeks.
