Social networking made the leap from desktops to mobile phones a long time ago, and a new report suggests that MySpace and Facebook still dominate even on the small screen.

Too bad the two market leaders may be doing more harm than good to mobile social networking. The report, published by ABI Research, says that nearly half (46 percent) of social networking users have visited one such network on a mobile phone. Among these mobile socializers, almost 70 percent of them visited MySpace, while another 67 percent hit Facebook.

Even though the mobile social networking landscape is rich with competitors, especially those innovating with location-based services, no other network garnered even 15 percent of mobile adoption. It should come as no surprise that the most important activities to mobile socializers are checking on new messages and comments from friends (50 percent of users), and posting status updates (45 percent) to let others know what they are doing.

“The social network is increasingly becoming a central hub for communication across online and mobile domains for many consumers,” said research director Michael Wolf. “To a degree, it allows them to centralize messaging, communication and even digital media consumption through a centralized property on various screens. We believe this centralization of a consumer’s digital lifestyle through social networks will only increase adoption of mobile social networking in coming years.”
