Looking to get into the iOS game and have no idea where to start when it comes to creating icons for your application? No worries, Jon Hicks, one of my favourite designers, has put together an Adobe CS5 Illustrator template for you to work from.
Included in the file is artboards for the multiple icons and a setup for the proper corner radius dimensions for all the icon sizes. It’s a great place to start. Hicks also points out that the template may work in CS4 or below, but he never tested it in those versions, so it could fall apart quickly.
