iOS (Jailbroken): The standard iPhone doesn't support multiple wallpapers. If you like to spice things up and have a jailbroken device, Pages+ allows you to customise the background for each page on your home screen.
Pages+ turns each of your iPhone's home screen pages into cards to help separate them. As well as setiing different images for each page, you can also customise the colours so each page has a different feel to it. Unfortunately, Pages+ only works with theme packs, and you can't customise the wallpapers with your own choices unless you make your own.
