I've searched all over the place on google and couldn't find a decent complete guide on making custom carrier graphics for the iPhone 4. I'm looking for a thorough guide in making a custom carrier logo/graphic using photoshop for the iPhone 4 that is complete and up-to-date. I've seen people on sites, such as macthemes.net, make carrier logos from pictures people provide them and make it in a universal size, cropped, and in different colors. I'd just like to know how they do this using photoshop or whatever program they use. Thanks guys.
