While September’s initial sales of the iPhone 5 dwarfed those of previous smart phones, consumers lashed out against the Maps feature, a navigation tool Apple developed to replace the Google-powered app that had come prepackaged on other iterations of the iPhone. But Apple Maps was a technological misfire, with its incorrect addresses, misplaced landmarks and warped renderings, and it earned the ire of many users. Apple CEO Tim Cook published an open letter on the company’s website apologizing for the app a week after the new iPhone went on sale, saying the tech giant was “extremely sorry” for the frustration the app had caused customers. The fallout continued in October with the resignation of Scott Forstall, the Apple executive who oversaw the development of Maps and who, according to the Wall Street Journal, refused to publicly apologize for the software’s shortcomings.
