Market research firm ChangeWave on Tuesday released the findings of a recent study analyzing iPhone 4 owner experiences and owner satisfaction. The study pitted Verizon Wireless’ iPhone 4 against the same model from AT&T, and sought to compare consumer experiences with the device at each carrier. Following years of complaints regarding poor service and dropped calls on AT&T, the question on everyone’s mind following the iPhone’s launch with Verizon Wireless was whether or not service quality would improve. According to ChangeWave’s findings, the answer is yes. In a survey of 4,068 customers, ChangeWave found that over the past 90 days, Verizon Wireless iPhone 4 users have dropped approximately 1.8% of calls while AT&T iPhone 4 owners dropped 4.8% of calls. Of course Verizon’s iPhone hasn’t even been on the market for 90 days and calling habits and frequency were not taken into account, so the results do become somewhat suspect. What’s more, ChangeWave notes that its survey started “several weeks after Verizon began offering the iPhone 4,” so we could be looking at just over a month of anecdotal Verizon Wireless data being compared to three months of anecdotal AT&T data. ChangeWave also found that Verizon Wireless iPhone owners are slightly more satisfied than AT&T iPhone 4 owners, with 82% saying they were very satisfied compared to 80% for AT&T.
