As it seem to be ok for the OS3.1 release, here is a new version.
You can add my repository on cydia : http://i.danstaface.net/deb/ and install vWallpaper.
– if you switch off vWallpaper, its destroy his content and respring, so you can see your wallpaper background.
– You can now downloading videos and Ringtones videos again within application.
As usual, i waiting for your feedback, so i can release it in public repository. Thanks
