Thought this was interesting. It seems that Mozilla's newly-christened Firefox OS has already gained favor with a number of carriers, including Deutsche Telekom, Smart, Sprint, Telecom Italia, Telefónica and Telenor. Vivo (Owned by Telefonica) plans to introduce the earliest handsets as soon as next year. ZTE (Known at this site for making affordable Android tablets) is making phones based on the HTML5-powered mobile operating system.
Could this mean that the mobile operating system market could have yet another contender? Only time will tell.
