It had been rumored for such a long time, and so many leaks got little details right, but overall the iPhone Duo has been Apple’s best-kept secret in years. Talking to Tom’s Guide and TechRadar in a new interview, Greg Joswiak, senior vice president of worldwide marketing, says he’s “super proud” of that.
“We put extra security on it, we didn’t talk about it to anyone,” he said. “We had a very funny codename, which I won’t even repeat, that had nothing to do with it.”
