The Nokia Lumia 900 for AT&T seams to be doing quite well in the U.S., leaving users looking for the Cyan version having to settle for the Black variant due to lack of availability. However if you are looking for something different, you may want to look out for the Magenta version of the device which may appear in time for Mother’s day.
The Magenta clad version of the Lumia 900 was spotted on a Microsoft Store demo screen and would likely make an appearance since the Nokia Lumia 800 also featured a Magenta variant.So all we can do is wait for Mother’s Day on May 13th and see if the Magenta variant of the Lumia 900 becomes a reality. Given the popularity of the Cyan variant of the device we can assume that the Magenta version would likely get a similar welcome.
So if you have been thinking of getting a brand new Lumia 900 you can now choose between Black, White, Cyan and Magenta.
