As internet titans eye the emerging mobile frontier, Yahoo! has decided not to go it alone. Yesterday, Yahoo made headlines when it announced a plan to open its mobile platform to outside developers. Today, Yahoo continued its openness campaign for mobile, announcing that it will create new versions of its mobile internet service to run on various platforms like Apple's iPhone and Google's Gphone.

According to a Reuters report, Yahoo's mobile boss Marco Boerries told attendees at the Consumer Electronics Show that the company plans to compete by offering internet services that work on existing – or future – phones, rather than banking only on its own in-house software. Boerries said he believes such a strategy will help Yahoo reach hundreds of millions of mobile users very quickly.

While many see systems like Google's Android, which would allow users to turn their phones in Gphones, as competition for Yahoo, Boerries dismissed the notion.

"Android for us is another mobile operating system like Microsoft's Windows Mobile and Nokia-backed Series 60 that we plan to support once it becomes a reality," Boerries.
