Apple quietly lost one of its most important iPhone and iPod executives late last year, according to a new report. Citing anonymous sources, 9to5Mac reports that David Tupman, Apple’s Vice President of iPhone and iPod engineering for over a decade, left the company late last year. Tupman was hired by the company shortly before the introduction of the original iPod, and was soon promoted to vice president of iPod engineering, a position that saw him help in the development of every iPod released to date. Tupman was also tapped to help build the iPhone, and, as a result, his title was expanded. In addition, Tupman is listed on around 70 Apple technology patents, including filings related to power and battery life management, noise-canceling ear buds, iPhone power adapters, and interaction with accessories. According to the report, a successor has yet to be named, but Apple is said to be actively pursuing a replacement from inside the company.
