UK retailer Carphone Warehouse briefly put up a registration page for the successor of the Lumia 800, the Lumia 900, on its website, before pulling it down.
The page, which can still be found in Google's cache, claims that the phone will be launched in June 2012 and will come with a 4.3-inch AMOLED touchscreen display with a WVGA resolution and covered with Corning Gorilla glass.
The phone has a front facing camera with a wide F/2.2 Carl Zeiss lens, an eight megapixel camera with 720p HD recording and what Nokia claims is "a massive battery for extra long standby times", with a 1830mAh capacity.
As expected, it will run on Windows Phone 7.5 which means that it will include Microsoft Zune, Bing, Xbox Live, Mobile Office as well as a slew of Nokia's own apps like Mix Radio, Nokia Drive and Nokia Music.
Carphone Warehouse has not said at what price the Nokia Lumia 900 will be available, but it is safe to assume that its launch will cause the price of the Lumia 800 to drop.
The latter is currently available for around £400 SIM free with the Lumia 710, the cheapest Nokia Windows Phone handset on the market, costing £300.
