Users can upload and edit photos and other graphics to make personalized wallpapers, and select from a catalog of audio tracks to create ringtones.
Content creators will earn 10 cents for each item purchased, credited to their Virgin Mobile accounts. The user-generated wallpapers will cost $1.99, and ringtones will cost $2.50.
The move is part of a broader effort by the youth-oriented mobile service to appeal to its core audience with more social networking features.
