Starting earlier today, Microsoft has confirmed that "100 more Windows Phone device/operator combos" are now getting the Lumia Cyan update. We confirmed that these are in addition to a large batch released yesterday, and it applies for those on the Preview for Developer program who previously could not get the Cyan update.
In order to check for the update, users can head into Settings > Phone update to see if one is waiting. Likewise, for some users launching the Preview for Developers app and disabling enrollment, then checking results in success as well (you can later re-enable the Preview after the update).
According to our poll of 10,000 Windows Phone users, 60% were already on Lumia Cyan by 3PM today. This number is likely to go higher after today's group of 100.
Unfortunately, we currently do not know which carrier/Lumia combos are part of this new 100, so you will just have to take your chance.
Let us know in comments if you received an update and on which phone and region!
