Verizon iPhone drop fewer calls than AT&T phones, but both networks have very satisfied customers. That’s what a study from research firm ChangeWave found in a recent survey of the differences between Verizon iPhone 4 users and their AT&T counterparts.

The survey found that, on average, 1.8 percent of Verizon users reported dropped calls, as compared to 4.5 percent on the AT&T iPhone. That fits in with anecdotal reports as well as network coverage tests that show Verizon has a more reliable voice network.

Both AT&T and Verizon get high marks in customer satisfaction: 82 percent of Verizon customers surveyed and 80 percent of AT&T customers surveyed said they were “very satisfied” with their iPhone 4.

Again, as with almost all of the surveys done comparing the two iPhone 4 networks, it comes down to a matter of preference. Those who want to use their iPhone primarily for voice calls may find a better fit at Verizon, whereas data users will probably be happier with AT&T.
