This is something that I would like to see in a software update. One of my few complaints about the iPhone is the lack of options that allow the user to customize the phone for their needs. Not only should the home screen show your wallpaper, but I think we should be allowed to move around the icons to where they work best for us. For example, I would rather have my SMS is the bottom right corner instead of iPod because I use SMS more often than the iPod. Hopefully we will see an update allowing this type of thing because I don't think we should have to hack our phones for a simple feature like that.
