The iPhone was Verizon’s top-performing smartphone during its most recent quarter, the company revealed during its quarterly earnings call today. All told, Apple’s smartphone made up 63 percent of Verizon’s smartphone device sales for the quarter, with 6.2 million sales out of a total of 9.9 million for smartphone hardware. Of the 6.2 million iPhones sold, Verizon CFO Fran Shammo said that half were 4G-capable, which means they were iPhone 5 handsets.
