Wow, could the world of open source mobile operating systems possibly become more fragmented? Yesterday, we noted that at this week's Intel Developer Forum (IDF) conference in San Francisco notebooks running on the open source Moblin OS are due to arrive, and Intel officials demonstrated a smartphone with an Atom chip running Moblin. Moblin will join Google's upcoming Chrome OS and Ubuntu in the fight to keep open source operating systems competitive on netbooks, and Intel's phone demo based on an open source OS represents the company's first foray into chips and platform technology for smartphones. Moblin/Intel phones may soon be competing with Android phones, and phones based on the upcoming open source version of Symbian's OS.

A press release issued by Mandriva and Turbolinux today announced they are joining the Moblin project and continuing their collaboration through Manbo Labs.

Manbo Labs employs Mandriva and Turbolinux engineers to develop the core components of a Linux distribution tailored for Atom processors.
