Here's when Orange Poland will upgrade their Windows Phones to Windows 10 Mobile

While we know more or less when Microsoft’s new Windows 10 Mobile flagships will be hitting the market (in the next 3-4 weeks) we don’t quite know when the upgrade will become available to existing Windows Phone 8.1 handsets.

Now WPWorld.pl reports that they have managed to lay their hands on Orange Poland’s upgrade plans, and that for some the wait will not be long.

According to their leak the upgrade will arrive in two rounds.  The first will start on the 14th December and will include the Lumia 630, 635, 735, 830 and 640.

The second, less lucky group will include the Lumia 520, 532, 625, 720, 820, 920, 925, 930, 1020, 1320 and will only start on the 1st February 2016.

Questions remain regarding the Lumia 530 and 1520, with both devices not marked for the upgrade. This does not of course tell us that no upgrade is planned, but only that they do not appear to be in either groups.

Of course, unlike other years, if one is desperate one can upgrade nearly any WP8.1 handset to Windows 10 Mobile via the Insider route, meaning I suspect a lot less grumbling with this OS upgrade than any other before.

Are these plans as our readers expected? Let us know below.
