WP Bench is a popular benchmarking app for Windows Phone 7 that tests various aspects of a smartphone such as web, speed, battery. This picture captured of the application in actions shows a phone Nokia Lumia 610 being tested. The phone has not been made official by Nokia yet however the rumors flying around suggest it will run the new version of Windows Phone called Tango. Tango as we know is aimed for low end phones and if the number 610 is anything to go by, it will be a lower end version of Lumia 800 or 710. MWC is right around the corner and only time will tell if Nokia announces this particular model.
