How to delete an unwanted icon
I downloaded a wallpaper and canot delete the icon i can delete apps like angry birds etc just not this wallpaper I downloadd
If you want to change the wallpaper go to Settings>Brightness and Wallpaper and select another wallpaper.
The wallpaper itself would be in the Cameral Roll or in the Saved Album in the photos app. Go there to delete the wallpaper from the iPad.
You delete the app the same way as you delete any app - tap and hold down on the icon until it wiggles then tap the X on the icon.
