Mobile social network Limbo's application for iPhone and iPod touch now features Facebook Connect.

Apple iPhone and iPod touch users can link their Limbo and Facebook accounts, enabling automatic status and activity updates that are shared between the two accounts. Limbo has run hundreds of mobile ad campaigns in 2009 for more than 60 brands, including Unilever, Yahoo, Verizon Wireless, the U.S. Navy, A&E, Chevrolet, Nissan, DirecTV and Playphone.

"We recognize that many people have Facebook accounts but not Limbo accounts, or have set up their friends in Facebook but not Limbo," said Rob Lawson, cofounder/CMO of Limbo, Burlingame, CA. "By working with Facebook Connect, these people can now use their Facebook login to bring all this data into Limbo without the need to re-register.

"In addition, a user can now set their status in Limbo and it is posted to both networks, minimizing the need to repeat this in multiple places," he said.

Limbo, founded in 2005, is a free, ad-supported mobile community with four million members and a monthly reach of more than five million people.

The privately-held company is backed by three venture capital funds: Azure Capital Partners, Draper Fisher Jurvetson and New Enterprises Associates.

Limbo's core demographic is 17-30-year-olds. The gender split is 55 percent female and 45 percent male.

Limbo with Facebook Connect is now available for free from Apple's App Store or at http://www.itunes.com/appstore.

In addition to the iPhone application, Limbo is available via SMS, the wired Web and the mobile Web.

With Facebook Connect, Limbo members can see their Facebook friends on Limbo without their friends having to be Limbo members.

They can also view the status of their friends on Limbo based on their Facebook status message or automatically set an "On Facebook" status for members who are logged on and active on Facebook.

The location-aware emphasis of the Limbo application lets consumers find and meet up with their friends to increase face time and real-world experiences, not just online interactions, according to Limbo.

"We work with all the major mobile operators such as Verizon, AT&T and Sprint and other partners such as Apple, Facebook and many media companies to get the word out about Limbo," Mr. Lawson said.

"We also run our own mobile marketing campaigns promoting Limbo, and are heavily reliant on our own members spreading Limbo virally to their friends," he said.
