News Corp's Fox Interactive Media said on Monday it plans to launch advertising-supported versions of its popular Internet social network MySpace and other properties for free on cell phones.

Aiming to court an audience adept at finding entertainment on mobile devices, MySpace will let its users send and receive messages, comment on pictures, post bulletins, update blogs, find friends and update their mood status on cell phones.

MySpace, which attracts some 80 million unique visitors per month in the United States, will offer a free version of its mobile application.

A more fully featured version is available to paying customers of AT&T Inc, Helio, which is the wireless joint venture of Earthlink Inc and SK Telecom, and other U.S. wireless subscribers.

The new version aims to open the ability to access MySpace even wider, executives said. Versions of Fox's, and film review site Rotten Tomatoes will also launch as part of the strategy.

We believe ultimately that people will access the Internet on mobile phones, Fox Interactive Senior Vice President John Smelzer said in an interview. We want to support that behavior as best we can. The more we can replicate what's going on online the better.

Millennial Media will provide the mobile advertising technology to support the new products.

Amit Kapur, vice president of business development for MySpace, also said the company is exploring development of a version tailored for Apple Inc's iPhone.
