Myriad Group, one of the largest mobile technology software companies, with over 2 billion devices, has announced today that it has acquired Xumii, a company that provides mobile social networks. Financial information was not disclosed, but Myriad Group stated that the acquisition was asset based.

Using a cloud computing architecture, Xumii integrates a mobile user’s phone contacts, social networks and instant messaging services into a single “social phonebook”. Mobile users can then simultaneously access Facebook, MySpace, Flickr, YouTube, Google Talk, Yahoo Messenger, AIM, Windows Live and other popular Internet services, sending messages, updating status and sharing photos and videos.

Xumii released an iPhone application back in February, that lets users have a mobile social address book that connects to AIM, Flickr, and other networks. This seems like a great fit for both companies, considering Myriad Group already provides software to all of the major phone manufacturers, as well as more than 30 mobile operators across the globe. Having Xumii’s technology with Myriad Group’s also established relationships with mobile operators makes this a perfect opportunity. Xumii’s 17 employees will be moving to Myriad Group as part of the acquisition.

Xumii is based in San Mateo, Calif. and Sydney, Australia, and has raised $5.5 million from CM Capital and Southern Cross Venture Partners in September 2008.
