I downloaded an app from the market awhile back with some autumn wallpapers. I chose one of them to be my wallpaper and then removed the app, but the wallpaper remained. I'd like to back that picture up to my sdcard before I wipe the phone and play around with a different rom. Does anyone know where assigned wallpapers get stored on the phone and how you can extract them to the sdcard? It's not on my sdcard already so I'm assuming it gets placed in one of the system folders.
