Carphone Warehouse apparently has an issue with getting new units of Microsoft's Lumia 950 and Lumia 950 XL smartphones. The listing for both Windows 10 Mobile devices on the UK-based retailer's website shows that delivery of new orders won't be made until January 29.
There's no word on why Carphone Warehouse is apparently unable to get shipments of the new Lumia smartphones out before that date. Other UK retailers like Amazon and the local Microsoft Store site show that they have the smartphones in stock for immediate shipment.
Thanks to Stephen for the tip
