Aside from the colour scheme one of the first things you will notice about the Apple iPhone 4 White is the display quality on the screen. The screen measures 3.5 inches and boasts an extremely high pixel resolution of 640x 960. This equates to 326 pixels per inch which is more than the human eye can perceive. Therefore you could hold it close to your eye and you still would not be able to make out the individual pixels. This results in unparalleled levels of display quality which makes viewing HD video footage on the screen an awe-inspiring experience. The TFT capacitive touchscreen is a pleasure to use and has virtually zero lag thanks to the power of the 1GHz Apple A4 processor (the same chip used in the Apple iPad) which offers ample computing power to handle the most demanding of tasks and applications with ease.
