Mobile virtual network provider Virgin Mobile isn't doing so well as of late, Engadget Mobile reports, with decreasing profits as well as a decreasing ARPU (average revenue per user). However, the blog points out that things can't be all bad since they're still actually turning a profit, which no other MVNO in the U.S. was capable of doing.

The company said that it thinks "it'll turn things around heading into '09 with the addition of Helio to its portfolio, which it confirms will be leveraged to offer new data services and feature-rich handsets, [which are] both concepts that bare-bones Virgin isn't accustomed to offering in the States," according to the blog. Mobile media-focused Helio did offer a nice array of music, video, and social networking services on its phones, so it remains to be seen how Virgin Mobile will leverage that going forward.
