We are less than 24 hours away from Nokia's Mobile World Congress 2012 press event and it appears one of the company's new Windows Phone devices has made its way online. A single image of an alleged Lumia 610 handset was posted to Twitter this weekend by an unofficial Nokia_N8 account. We are unable to confirm the authenticity of the image, but specifications for the rumored device appear to have leaked too.

BGR India claims the Lumia 610 will feature a 3.2-inch display, 3-megapixel camera, and will run Windows Phone Tango. The site says the handset will be priced at around $233 when it is launched in India. We have heard a number of details about Tango and its timing, including the fact that it will push the minimum hardware requirements down to just 256MB RAM. Some alleged screenshots of Windows Phone Tango leaked earlier this month, appearing to confirm the RAM limit and new 3-megapixel camera support. With the Lumia 610 passing certification in Indonesia recently, there is a good chance we'll learn more about Windows Phone Tango and Nokia's handset plans at Mobile World Congress, which kicks off tomorrow morning.
