* KDDI, Immersion join wireless Linux group LiMo
* LiMo still lacks support from top telephone makers
The focus of the cellphone market has been shifting to software development since Google Inc GOOG.O and Apple IncAAPL.O entered the mobile market in the past two years, with phone vendors and operators increasingly looking for open source alternatives such as LiMo to cut costs.
The market for software platforms on cellphones is led by Nokia's NOK1V.HE Symbian operating system, but it has lost much ground over the last year to Apple and BlackBerry maker Research in Motion Ltd RIMM.ORIM.TO.
Computer operating system Linux has had little success with cellphones so far, but its role is increasing with the LiMo platform and Google is using Linux for its Android platform.
Linux is the most popular type of free or so-called open source computer operating system available to the public to be used, revised and shared. Linux suppliers earn money selling improvements and technical services and Linux competes directly with Microsoft Corp MSFT.O, which charges for its Windows software and opposes freely sharing its code.
LiMo also said Japanese mobile carrier KDDI Corp 9433.T and touch screen company Immersion Corp IMMR.O had joined the not-for-profit foundation. But LiMo has been missing support from the largest cellphone vendors. So far smaller phone makers NEC, Panasonic and Motorola Inc MOT.N have unveiled in total 42 phones using its software. At the same time, all the top handset vendors, except Nokia, have promised to produce phone models running Android software.
LiMo hopes to benefit from its focus on giving greater say over software development to telecommunications operators. Its key members -- Vodafone Group Plc VOD.L, France Telecom SA's FTE.PA Orange, Japan's NTT DoCoMo Inc 9437.T, South Korea's SK Telecom Co Ltd 017670.KS, Telefonica SA TEF.MC and U.S. operator Verizon Wireless, a venture between Verizon Communications In VZ.N and Vodafone -- have pledged to introduce LiMo phones in 2009.
