Windows 10 Mobile upgrade schedule leaks

Windows 10 Mobile will begin rolling out to older Lumia devices in mid-December, if a recently leaked operator schedule is to be believed.
We already know that Windows 10 Mobile is coming in the next few weeks, thanks to the imminent launch of the Lumia 950 and Lumia 950 XL. What we don’t know is when older Windows Phone 8.1-powered Lumia devices will be getting their promised upgrade.
Now, a freshly leaked update schedule from Orange Poland offers some insight into that particular conundrum.
As reported by WMPoweruser, the Windows 10 Mobile update will begin on December 14. That’s when Orange Poland will be pushing the update to the Lumia 630, 635, 735, 830, and Lumia 640.
According to the schedule, a second larger batch of Lumia devices will be getting the Windows 10 Mobile update from February 1 2016. This will include the Lumia 520, 532, 625, 720, 820, 920, 925, 930, 1020, and 1320.

The eagle-eyed and Microsoft/Nokia-savvy among you will have noticed that the Lumia 530 and Lumia 1520 are missing from that list. We can’t imagine that they won’t be getting the upgrade though.
This is far from an official confirmation, nor does it necessarily reflect when other territories will be getting the Windows 10 Mobile upgrade. It is a handy pointer that we shouldn’t have long to wait, though.
