I don’t know, what to make of this? Tom Warren is one of those sources who came up with many details regarding both Lumia 920 and 820 before their launch. Now in a tweet, replying to which color of Lumia 920, he will choose, he just said “Cyan, of course”. Is this a hint of Cyan version of Lumia 920 coming later.
Frankly speaking, many of Lumia fans were slightly disappointed on not seeing Cyan as a possible color choice, when Lumia 920 was revealed. So, may be Nokia has opted to bring a Cyan Lumia 920 later as a special edition model as Cyan was the hottest color choice when Lumia 900 was released.
