Skyfire has quietly said it was dropping Symbian and Windows Mobile support for its browser. The two would phase out at the end of 2010 and would only see the more advanced Android and iOS 2.0 versions available in the near future. Both being initially free made them unsustainable, but the age of the apps and problems with the platforms themselves made it unrealistic to charge a device for a product that would be dropped earlier, Skyfire said.
