ChangeWave conducted a survey of 4,068 wireless customers to determine the difference between Verizon iPhone owners and AT&T iPhone owners. The survey was completed on March 28, and it takes into account Verizon owners' initial response to the iPhone's performance on the CDMA network.
The results show that, overall, Verizon iPhone owners are equally as satisfied as their AT&T counterparts with 82 percent of Verizon owners and 80 percent of AT&T owners reporting they are very satisfied with their current service. Dropped calls on the two carriers differed greatly with AT&T iPhone customers reporting up to 4.8 percent of dropped calls and Verizon customers coming in with a much lower 1.8 percent.
Over the two-year survey, Verizon's overall dropped call rate has decreased from 2.7 percent in 2008 to 1.4 percent in March 2011. AT&T, on the other hand, has shown an increase from 3.6 percent in 2008 to the current 4.6 percent in March 2011. This 4.6 percent is encouraging and shows that AT&T is trying to address this problem. Though its dropped call rate is higher than 2008, this rate is slowly falling down from a high of 6 percent reported by AT&T iPhone owners in September 2010.
