This is an illustration I did a while back and I have dusted it off for this iPhone/iPod Touch Wallpaper (480 x 320 pixels). If you need one for your iPad (1024 x 1024 pixels) there is another wallpaper in todays other post.
Search – how to install an iPhone wallpaper – at your favorite search service for instructions on how to install the wallpaper on your iPhone or iPod Touch. The process is relatively easy and in-part it will entail copying the illustration in this post to your computer.
(I plan on making wallpapers for the iPhone and iPod Touch available here on a regular basis, around mid-month. You can find all the Wallpapers up at the top of the page by selecting the Wallpaper tab)
