With the iPad and iPhone 4, there are as many, if not more, different size icons to create for iOS than there are for desktop apps. While there are plenty of templates and reference sheets for Photoshop users (see Cocoia) I prefer to use Illustrator CS5 to create mine. So I’ve made my own template, and it’s available here if you find it useful too!
