Apple's senior VP for iOS, Scott Forstall, was indirectly responsible for the leak of an iPhone 4 prototype in 2010, a new Businessweek profile suggests. A former Apple manager claims that Forstall persuaded the company's CEO at the time, Steve Jobs, to allow dozens of engineers to carry prototypes so they could do better testing of network performance and reduce dropped calls. It was one of Forstall's engineers who accidentally left an iPhone 4 in a pub, which eventually resulted in a Gizmodo hands-on piece and a high-profile criminal investigation.
