Messed up Wallpaper.app!

[PowerFullMac]

Right, I changed the name of my Wallpaper app to Camera and changed the icon just to mess about and make it look like a iPhone but then a update to Wallpaper.app was relwased though Installer so I installed it but now I have Camera which is a old version and Wallpaper which is the new version, which I dont mind because I could easily just rename some files to fix that, but the new Wallpaper.app wont show up on the SpringBoard, I can only run it from Finder. Any ideas?

Thanks in advance!
