  "Testing performance in the field. Apple engineers tested iPhone 4 in a variety of scenarios, environments, and conditions in order to gauge performance. They spent thousands of hours in cities in the U.S. and throughout the world testing iPhone 4 call quality, dropped-call performance, call origination and termination, and in-service time. They tested iPhone 4 while stationary, at high and low speeds, and in urban, dense urban, and highway environments. In low-coverage areas and good-coverage areas, during peak and off-peak hours iPhone 4 was field-tested in nearly every possible coverage scenario across different vendor and carrier equipment all over the world."

  They did, but even so that is hardly a scientific test, or an optimal way to evaluate all the various designs that they also tried.
