David Pogue tried out the Verizon iPhone 4:
In San Francisco, the AT&T phone dropped the call four times in 30 minutes of driving; the Verizon phone never did. The Verizon iPhone also held its line in several Manhattan intersections where the AT&T call died. At a Kennedy airport gate, the AT&T phone couldn’t even find a signal; the Verizon dialed with a smug yawn. Most impressively, the Verizon iPhone effortlessly made calls in the Cellphone Signal Torture Chamber of Doom: my house.
