I finally have a selection of cases to fit your iPhone 3G, iPhone 3GS, iPhone 4, and iPad up and available in my cafe press shop. There are multiple designs you can choose from, and if you see a design featured elsewhere in my shop that is not available on one of these cases, just email or PM me and I'll add it for you.
