iPhone 4G dreamed in the wild

Since the public has come down after speculating on the iPad followed by its announcement, it is time we think remember the next gen iPhone 4G and show you some of the latest mock-ups on it. Not just that they appear in an unprogressive fashion, but that this particular one found accidentally on the Web runs pretty close to what everyone is expecting. It gives suggestions on a front camera, microSD expansion slot which will never be there but no matter, bright and happy color schemes. iPhone 4G already has a rather straight forward “must have” hardware and feature list. But from the design point of view, how could it evolve? Even free-minded sketches show no paths of alternative. Whether it is good or bad for the iPhone is quite a question for the ages, so have your say on future of iPhone's design in comments.
