Even though iPhone 4 is rendering 4 times the pixels on its new, high resolution Retina display, it does more faster than the recent iPhone 3Gs! iPhone 4 consistently loads and renders web pages faster than the snappy iPhone 3Gs.
Part of the speed increase is due to the faster Apple A4 processor (like the iPad), another factor is the new HSUPA support in iPhone 4. That means in supported areas, iPhone 4 will have up to 60% faster downloads and up to 500% faster uploads. This test result is likely to have reflected both these factors.
