Microsoft will be releasing the Lumia Cyan update to more people who have installed the Windows Phone 8.1 Preview for Developers build on their smartphones, with the aim of expanding that release to even more phones in the days ahead.
In a post on the Microsoft Answers forum, forum moderator Mike Mongeau stated:
So, first things first: today we're releasing the Lumia Cyan update for another chunk of Preview for Developer devices. We'll be closely monitoring the success of this update on those phones. So, let us know if you are offered the update and if you have any issues! If all goes well, expect broader communication for the availability of even more phones (lots more!) over the next few days. Thanks for holding tight folks -- we're almost there.
Hopefully this means more people who have already downloaded the Developer Preview version of Windows Phone 8.1 on their Lumia devices will be able to get the Cyan update sooner rather than later.
Thanks to Mike and Andrea for the tips!
