comScore, a measurement firm that focuses on all things digital, released a study that shows 30.8 percent of smartphone users accessed social networking sites via their mobile browser in January, up 8.3 percent from 22.5 percent one year ago.

According to the report, access to Facebook via mobile browser grew 112 percent in the past year, while Twitter experienced a 347 percent jump.

“Social networking remains one of the most popular and fastest-growing behaviors on both the PC-based Internet and the mobile Web,” said Mark Donovan, comScore senior vice president of mobile, in a statement. “Social media is a natural sweet spot for mobile since mobile devices are at the center of how people communicate with their circle of friends, whether by phone, text, e-mail, or, increasingly, accessing social networking sites via a mobile browser.”

At 30.8 percent adoption by smartphone users, the higher end devices proved to be the real drivers for mobile social networking. By comparison, just 6.8 percent of feature phone users accessed social networking sites on their mobile phones.
