If you hate your standard background why not try something customized for the iPhone UI? With Home Screen Wallpapers HD you get custom images based around your homescreen for all your apps! Make your iPhone apps look like there on a book case, set of blue prints or one of 80 other designs!
**NOTE**
You can use this app on the iPhone 3G but it doesnt support backgrounds nativity on 4.0! If you have a wallpaper it means this will work and it should work.
