For people living in Poland and owning a Lumia 640 smartphone connected to T-Mobile, it’s going to be a lucky jackpot. All Windows 8 and Windows 8.1 users are likely to get an update to move to Windows 10 Mobile. According to the latest report, the carrier has already started updates over-the-air for Lumia 640, in the reported first few instances of such updates for older versions of Windows Phones that aren’t a part of Windows Insider Program.
T-Mobile support page online indicates that this update is all set to take the Lumia 640 up to software version 02177.00000.15184.36002. It further added that the same update is to be released in different batches so that not every Lumia 640 user can get the update at the very same time. However, there’s still no confirmation as to when this download can be available on other mobiles outside Poland.
