But what is particularly interesting is that when you put the old iPhone Simulator next to the new iPhone 4 Simulator on the same computer screen, and view similar web pages on each. This really brings home how much higher the resolution of the new iPhone 4 screen is.
Side by side the new iPhone Simulator is literally double the size of the old in both dimensions. Which clearly shows how on the same sized iPhone we now have 4 pixels for every one we had on older iPhones LCDs! Amazing stuff!
