PALO ALTO: Facebook will introduce new mobile services in future but will not develop its own smartphone, Mark Zuckerberg has said.

Speaking to TechCrunch, the Facebook ceo said that he was planning to agree partnership deals with third parties to provide more integrated Facebook software for phones.

"We can do a single sign-on if we do a good integration with a phone, rather than just doing something where you go to an app and it's automatically social or having to sign into each app individually," he added.

As part of this strategy, the social media firm could also launch its own adaptation of the Google Android smartphone operating system.

Zuckerberg said: "For platforms that are really important, but are hard to penetrate, like iPhone, we'll just do as much as we can. For Android, we can customize it a bit more."

But, contrary to recent industry rumours, the plans do not include launching a new handset, the Facebook ceo confirmed.

"Our goal is to have Facebook be everywhere and everything be social rather than a specific device," Zuckerberg added.

This "social web" strategy has already been employed in a limited way through services like Facebook Connect, through which members of the network can use their accounts to leave comments and make recommendations on third party websites.

According to data from the Future Foundation, around 45% of the total time spent by users on the mobile web is already spent on Facebook.
