Screenshots of Nokia's newest operating system, Symbian^4, have been leaked, tech news site Softpedia reported on Monday.
Symbian^4, an operating system designated by Nokia for use on its mid-ranged devices, has been built on QT and Orbit to allow software developers to build applications for the platform quickly and aims to bring an improved and easier user experience.
