Hello,

I thought I'd share another tutorial I've made if thats okay. Sometimes the most basic tutorials are the most useful...

I wrote a quick walkthrough on how to create an iPhone wallpaper from your own image using iPhoto 08. Then how to sync it to your iPhone and set it as your iPhone wallpaper.

I used this method to create an iPhone wallpaper which matched one of my OS X desktop wallpapers.
