The cyan version of the Nokia Lumia 900 with AT&T is out of stock on Amazon and quite a long 1-2 week backorder is mentioned.
The black version is still in stock. Interestingly in Europe the black version of the Lumia 800 was the top seller. Maybe this points towards the Lumia 900 becoming somewhat of a fashion statement that customers buy rather the more obscure cyan version than the matte black.
Now does that mean the Lumia is a bestseller or did Nokia just not ship enough? Let’s hope for the former.
