Mobile World Live’s Matt Ablott has posted an interview with Sprint CEO Dan Hesse in which he talks about the company’s decision to sell the iPhone. Hesse noted that iPhone sales have exceeded Sprint’s expectations. And four out of every 10 iPhones sold by Sprint are to new customers, roughly double the rate of AT&T and Verizon – implying that Sprint is taking customers away from the competition.

Hesse also addressed analysis that Sprint and others pay heavier-than-typical subsidies to sell the iPhone. He said that iPhone customers are more profitable than others because there’s lower “churn” – the term the industry uses to describe the rate at which customers leave services over time. Hesse added that Sprint iPhone 4 users are using less data on average than high-end Android 4G device.
