If you just bought a PlayBook tablet, one of the first things you want to do is customize it. Start by changing the wallpaper. Go into your photo or wallpaper collection and browse to the image you want.
Swipe your finger from the top bezel down. Then tap on the Set as Wallpaper icon. You'll see a pop-up letting you know it's resetting the wallpaper to that image.
That’s all there is to it. Enjoy!
