MMMOOO just notified me that they have a free wallpaper shifter app available in the BlackBerry Sync Store. I know we get asked about this type of app from time to time, yes there is an app for that and yes it’s free thanks to MMMOOO with Wallpaper Shifter v1.0.
The app is OTA but ONLY works with OS 4.7 and higher. Not bad though, since it will shift your wallpaper without causing your BlackBerry to slow down. You decide how often and from what files your pics rotate. It’s a nice way to watch all your pics.
