The security obsessed Apple has accidentally revealed that it is developing the ARM processor in-house.

Wei-han Lien, Chief of Apple's chip team, posted his job description to LinkedIn, revealing that he is heading the "ARM CPU architecture team for iPhone."

The only problems is that while everyone knew the iPhone had an ARM chip, no one knew that Apple had a CPU architecture team to develop it.

Lien was part of PA Semi, the chip maker which was bought by Apple in April.
