Timeline for Windows 10 Mobile rollout for existing Lumia devices leaked.

Windows 10 Mobile is on their way to RTM with rumors that the Lumia 950, Lumia 950 XL and the Lumia 550 will be arriving store shelves later this month or early December. As the first wave of Windows 10 Mobile devices becomes available to customers, it’s fairly simple to understand that existing Lumia users would ask if every they get Windows 10 on existing Lumia devices and when specifically.

Before, we relied on bits and pieces of information but today we learned something more specific with an actual timeline of rolling out Windows 10 Mobile from carrier Orange in Poland and will become available in two waves.

The first wave of devices to get Windows 10 Mobile from the carrier would be the Lumia 630, Lumia 635, Lumia 640, Lumia 735 and Lumia 830 with the rollout commencing on December 14. The second wave however would come later in February 1st of next year and the list of devices to receive the Windows 10 upgrade would include the Lumia 520, Lumia 532, Lumia 625, Lumia 720, Lumia 820, Lumia 920, Lumia 925, Lumia 930, Lumia 1020 and the Lumia 1320.

While the timeline only involves Orange in Poland, we’d then expect other carriers to follow as the Windows 10 update on Lumia has been on the top list for customers in terms of operating system upgrades and that is users are even more excited tha Windows 10 Mobile brings alot of new features and functionality of existing Lumia devices.
