The survey, which also looked at T-Mobile and Sprint, found that Verizon led the pack overall in the lowest number of dropped calls across the industry. Verizon mobile phone customers in general reported that on average only 1.4 percent of their calls dropped over the past 90 days. T-Mobile took second place with 2.3 percent dropped calls, followed by Sprint with 2.7 percent.

Verizon also outscored AT&T with future iPhone owners. Among those who plan to buy an iPhone 4 down the road, 46 percent said they'll go with Verizon, while only 27 percent are eyeing AT&T.
