Mr. Egan seems to have left out the part of the Consumer Reports test where they also tested the iPhone 3GS and a Palm Pre, both on the at&t network. In fact, he says:
And we don’t know how the observed effect is, or is not, similar to other devices.
Well, actually, we do. The iPhone 4 was the only phone to suffer from the antenna issue in their test. So no matter how “uncontrolled” and “unscientific” the tests were, I think Mr. Egan has a little more explaining to do before he can call the tests “flawed.”
