Stunning Display
Apple’s stunning 3.5 inch Retina display has 960 x 640 pixels — four times as many pixels as the iPhone 3GS and 78 per cent of the pixels on an iPad. The resulting 326 pixels per inch is so dense that the human eye is unable to distinguish individual pixels when the phone is held at a normal distance, making text, images and video look sharper, smoother and more realistic than ever before on an electronic display.
5 Megapixel Camera
iPhone 4 features a new 5 megapixel autofocus camera with a 5x digital zoom, a backside illuminated sensor and built-in LED flash that allows you to take amazing pictures even in low light and dark environments. iPhone 4 lets you record and edit incredible HD video and the popular tap to focus feature now works while recording video. You can use the iPhone 4‘s LED flash for both still photography and video recording.
