Microsoft has talked a great deal about Windows Mobile being the "third ecosystem" in the smartphone universe. Of course BlackBerry would also like that distinction. And while some argue it's too little too late, it's also possible that Mozilla's HTML5-based Firefox OS will have a meaningful seat at the mobile platform table -- at least in selected markets.
Yesterday at Mobile World Congress, the company announced a wide range of mobile operators that had made a "commitment" to Firefox OS. Those carriers include: América Móvil, China Unicom, Deutsche Telekom, Etisalat, Hutchison Three Group, KDDI, KT, MegaFon, Qtel, SingTel, Smart, Sprint, Telecom Italia Group, Telefónica, Telenor, TMN and VimpelCom.
Mozilla announced that the first group of FOS handsets will go on sale in Brazil, Colombia, Hungary, Mexico, Montenegro, Poland, Serbia, Spain and Venezuela. Hardware makers Huawei, LG, ZTE and Sony have all embraced the platform -- though Samsung has publicly said it isn't interested.
While it's unlikely to appeal to existing high-end smartphone users, it's quite possible that FOS could displace Android at the smartphone entry level in developing markets. Many carriers and OEMs are hungry for Android alternatives, which partly explains the long list of operators on board.
