I visited AT&T’s website just to see if AT&T was still folowing through with their promised push of the Lumia 900 and here is what I found is a good sign. Not only is the main slider featuring the Lumia 900 it is featuring all three flavors of the device. Matte Black, Cyan and Glossy White are available. Sort of.
It appears that though the Matte Black and Glossy White are in-stock on the website the Cyan will prompt you with a 5-7 day shipping time.
