AT&T’s dependability is improving while Verizon’s dropped-call rate hits a record low

In its first survey of iPhone owners since Apple AAPL began selling a version of the iPhone 4 through Verizon VZ , ChangeWave Research found that the overall satisfaction of Verizon iPhone owners was “virtually indistinguishable” from that of those using the AT&T T version — despite the fact that AT&T continues to drop calls more than any other major U.S. carrier.

82% of Verizon customers pronounced themselves “very satisfied” with their iPhones versus 80% of AT&T owners, while 16% and 18%, respectively, said they were “somewhat satisfied.”

Meanwhile, both companies seem to be making progress on the dropped-call front. The frequency of dropped calls over the past 90 days among AT&T respondents dropped from a high of 6% in September to 4.6% in March. Among all Verizon customers, the frequency was 1.4%, the lowest ever recorded in a ChangeWave survey. For Verizon iPhone owners, however, the rate was slightly higher: 1.8%
