If the iPhone 3GS was a smaller step forward, the iPhone 4 was a big one - it had a new, sleeker, more modern look, and massively increased the pixel count while keeping the same 3.5-inch display size (this was the first Retina display). It was the first iPhone with a front-facing camera, the first iPhone with some level of multitasking, and one of the most significant iPhones Apple has ever made.
