Not everyone wants their iPhone 4 to look like a candy bar and equally not everyone wants theirs to look like something more suited to space travel. Fortunately there is a huge choice of wallpapers either self produced or purchased. If you decide to purchase wallpapers it is certainly best to shop around. Personally I would avoid buying them directly from the web there are a number of apps available from the app store and these will have passed muster with Apple.
