As many as a third of iPhone owners may mistakenly believe that they own a “4G” handset, according to a new survey. Retrovo’s latest Gadgetology Report found that 34 percent of iPhone owners reported that they “already own one” when asked if they were planning to purchase a 4G-capable handset this year. Notably, however, 40 percent of current iPhone owners said they will buy the next iPhone even if it doesn’t have 4G, followed by 21 percent who said they would consider it; by comparison, these numbers were eight percent and 12 percent for Android owners, and 23 percent and 18 percent for BlackBerry owners, respectively. The survey was based on a sample size of more than 1,000 people “distributed across gender, age, income and location in the United States.”
