Konami has announced that it's adding Old Snake and BB Corps to its Japanese cell phone wallpaper service Kisekae Changer. One download will run users ¥525 (US$5.16). The publicity for MGS4 really must one of the longest PR campaigns (if not longest) for a released title. Guess that's not a bad thing for those who are really into Metal Gear Solid 4, no? More BB images after the jump.
