Consumer Reports won't recommend the Verizon iPhone because it has the same problems with the antenna as the AT&T version. In a blog post, Consumer Reports details its tests.
The Verizon iPhone 4 closely resembles the original AT&T iPhone 4 in many positive respects, including offering great multimedia functionality, a sharp screen, and the best MP3 player we've seen on a phone. Unfortunately, it also shares with its sibling the possibility of compromised performance in low-signal conditions when used without a bumper or case.
However, there haven't been widespread complaints about the Verizon iPhone. Why? Verizon has better coverage.
Consumer Reports noted that the iPhone still scores high in its ratings. The advice for the Verizon iPhone 4 is the same as it ever was: Buy a bumper case.
Fair enough. In fact, that's great advice. If you buy an iPhone 4 buy a bumper. Frankly, consumers don't seem to care. They keep buying up those iPhone 4s.
