That’s it, you’re all set. The next time you turn your iPhone on, you’ll be greeted by the picture of your choice. Unfortunately, that’s just about the only place you’ll see wallpaper with the iPhone. It doesn’t even appear on the home screen, which remains a dull black no matter what.

And, annoyingly, there doesn't appear to be any easy way to go back to not having wallpaper once you start using it. It seems you have to stop syncing or delete that image from your iPhone. All you can easily do, apparently, is change the wallpaper to another picture.

In addition to your own pictures, there are free wallpaper sites out there that have images you can download already formatted to fit smoothly on the iPhone's 320 x 480 pixel resolution display. Simply download them to your computer and sync them to your iPhone.
