Burn-In Remover

Burn-In Remover will help you to remove the nasty burn-ins and image retentions on the pretty screen on your iDevice.
Image retention and burn-in is and effect on LCD displays, where the an old screen image seems to be blending with the current. For instance if youve used one application a lot, some parts of its interface elements (like an address bar) might still be faintly visible when you leave the app. This is especially visible on grey/dark backgrounds. Use this app to remove this as fast as possible.

If your screen is suspect to severe burn-in, this app will help nothing. In that case, refer to the shop you bought your iDevice.
