IPhone S for Speed... Again

The iPhone 3G S
Speed: To me, this is the most important feature of the new iPhone 3G S. In fact, the "S" in the name stands for speed. During my week of testing, the new model proved dramatically snappier in every way than my iPhone 3G. Its processor is 50% faster than in the prior model, and it sports a new graphics chip.
