Version 1.3 of FontShop's FontShuffle app is now available in the iTunes App Store (still free). All the type samples and graphics, representing more than 900 fonts, are now optimized for the Retina display of iPhone 4. Any simulation of the new graphics here in the blog (see full size) can only go so far, but if you are lucky enough to see the app live on an iPhone 4 you can't help but feel you are sitting at a light table, looking at high-res prepress repro film.
