KELLNER: Verizon’s iPhone outshines AT&T’s

In theory, there should be little difference between the disparate versions of Apple's iPhone that work on the wireless networks of Verizon and AT&T. As I said, that's the theory. I was pleasantly surprised by the reality, however. Published March 1, 2011
