Vringo, a US provider of software platforms for mobile social and video applications, launched its Facetones app for Android via BlueVia, Telefonica’s global developer platform. Facetones creates an automated video slideshow using friends’ photos from social networks such as Facebook and then plays this video slideshow each time a user makes or receives a call. It will initially be available on Telefonica’s Application Store (Mstore) in several global markets.
