According to Japan's Daily Yomiuri, NTT DoCoMo is partnering with Samsung to develop phones running the open-source Tizen operating system, with the first handsets reaching the market next year. According to the Yomiuri, other mobile carriers are also getting behind the development of Tizen because they "fear the hegemony" of Apple and Google. We've heard about Tizen as far back as September of 2011 -- this Linux-based (and Intel-backed) software came about when Nokia's MeeGo OS bit the dust, and we've already seen evidence of a Tizen-based Galaxy S III.
