We reported yesterday that AT&T had listed both the black and cyan Lumia 900's as backordered on their site and it was increasingly harder to find them in the stores (though we have heard that certain stores still have stock). However, we were a bit cautious to suggest that it was because the Lumias were selling out due to popularity. After all there was a good chance stock was being pulled to be re-flashed with the new firmware to fix those data-connection issues.
While we're still not prepared to call the Lumia 900 a best-seller without firm numbers, there is seemingly more good news. On Amazon Wireless, the matte-black Lumia 900 has been holding the #1 spot under "AT&T phones with contracts" for one week now with the cyan variant close behind at number two. Just as impressive, the matte-black Lumia 900 has the #1 spot across all carriers. Yowza.
