Following the official unveiling of the white Nokia Lumia 800 yesterday, Finnish phone manufacturer Nokia has accidentally leaked plans to launch a white hued rendition of the device’s US locked sibling, the Nokia Lumia 900.

Leaking via the company’s official Facebook page, the white Nokia Lumia 900 image is distinguishable from its officially confirmed sub-sized sibling thanks to its Nokia Windows Phone exclusive front-facing camera.

Looking to promote yesterday’s unveiling of the lusciously hued white Lumia 800, Nokia’s Facebook gaffe saw the 4G capable device, which largely resembles the 800, posted alongside the link:  “Find out how our designers came up with the perfect pigment for the new white Nokia Lumia 800.”

Nokia Lumia 900 Specs

Formally outed at CES 2012 last month the Nokia Lumia 900 boasts a 4.3-inch ClearBlack AMOLED display, compared to the 3.7-inch Nokia Lumia 800, with Microsoft’s Windows Phone Mango OS further plumped by a 1.4GHz processor and a host of Nokia exclusive WP7 apps including Nokia Drive.

On the entertainment front the handset boasts an 8-megapixel rear-mounted camera with 720p HD video recording capabilities and, unlike the Lumia 800, a second, front-facing snapper. Rising to the needs and expectations of its US users the 900 plays host to 4G LTE connectivity.
