Microsoft announces which Lumia handsets will get upgraded to Windows 10 Mobile at launch

In November 2014, Microsoft said that “there will be Windows 10 upgrades for all Lumia Windows Phone 8 devices” – a fairly unequivocal statement that leaves no doubt that all of the company’s devices released with WP8 onwards would be upgraded. But details now provided by Microsoft on its website suggest that availability of Windows 10 Mobile will be limited to only certain devices – at least at first.
