Thank you! iPhone Resource will obviously have templates like this with actual sample icons (and some recreated Apple icons) once it’s out. Good luck designing your mobile apps for iPhone! 1. Setup Photoshop If you’re designing for iPhone 4 you’re designing for a high-res retina screen. 2 pixel lines appear as 1 point when they’re shown on screen. InVision is a product design, collaboration and workflow platform making design better, faster and smarter. This will no longer be visible on the team page.
