Playboy offered me $60/year for access. I figured, what's $60/year? I went ahead and subscribed.
Image sources of the following wallpapers are from Playboy, then modified by myself: Jillian Beyor, Marie Francis (my new favorite), Cassie Keller, Ashlyn Letizzia, and Carlie Christine.
Playboy has plenty of "Cyber Girls" who are just all naked, but are too pretty not to put on as wallpaper for my BlackBerry. I can't post them here though; management may have a problem with it.
