MySpace.com has established an exclusive partnership with Helio, a mobile phone venture owned by EarthLink Inc. and South Korea’s SK Telecom Co., to offer features of its social-networking Web site on Helio’s service and cell phones set to launch this spring.

Helio phones will give users the ability to take photos of themselves and post them to MySpace with an invitation as well as create Web log entries and send messages to friends.

L.A.-based MySpace, which is owned by News Corp., has about 55 million users, many of them in key 18- to 34-year-old demographic, who connect with each other via Web profiles, blogs, instant messaging, photo galleries and user forums. Helio aims to connect with this young, tech-savvy age group with its service and phones.

Helio hasn’t announced prices for the phones or the service. Mobile access to MySpace will be free for Helio users.

EarthLink and SK are investing $440 million in Helio over the next three years.
