John Carmack loves the iPhone SDK. Last year he said he was working on an app that will take the iPhone to its graphical limits and Doom Resurrection is probably it. Thankfully, it was developed with the current crop of iPhones in mind so you don’t have to have the new iPhone 3G S to play it. But if the iPhone 3G supports games this graphically awesome, what can the iPhone 3G S with OpenGL support and a 600MHz CPU do? The mind boggles.
