Consumer Reports found that the Verizon iPhone 4 has the as the AT&T iPhone 4, making it just as likely to drop a call if it is not "held properly" or protected with a case of some sort.

Seems odd that AT&T has 2.5 times more dropped calls, but virtually identical customer satisfaction.It is worth noting that the same ChangeWave survey also found that customer satisfaction with the iPhone 4 is virtually identical at both Verizon and AT&T. You would think that AT&T customers would be less likely to be "very satisfied" or "somewhat satisfied" with the iPhone 4 if the probability of dropping a call is 250 percent higher. Of course, maybe AT&T customers have become numb to those types of issues and have lower expectations than their Verizon counterparts.

Does my iPhone 4 drop calls? Sometimes. I can even identify for you the specific quarter mile stretch of the road where it is most likely to happen, but that is a function of a dead zone in AT&T's coverage, rather than an issue with the iPhone 4 specifically. My own experience, though--at least here in the Houston area--is that no smartphone, and no wireless provider is perfect, and that the odds of dropping a call are about the same no matter how you slice it.
