The iPhone 4 got a preemptive teardown on Monday courtesy of CEO Steve Jobs at Apple's Worldwide Developers Conference. One of the key goals is to pack more features and functionality into a smaller space: at 9.3mm thick, the device will be 24 percent thinner than its predecessor.
Like the iPad, the A4 uses an ARM central processing unit, or CPU, designed by Intrinsity and manufactured by Samsung . The extra horsepower of the A4--compared with its slower cousin in the iPhone 3GS--and the accompanying graphics engine will help push around all of the additional pixels in the screen's high- density 940x640-pixel "Retina Display" --which has, incredibly, four times more pixels than previous iPhone models and boasts a 800:1 contrast ratio. The iPhone 4 also now uses a Micro-SIM format, like the iPad, and accommodates 16GB or 32GB of Flash memory, also presumably from Samsung.
