Apple looks like its planning to use the iPhone OS to power more than the iPhone, iPod touch and iPad, according to a new job posting for a full-time engineering manager to work on the iPhone OS platform.

Apple’s ad is looking for an engineer to focus on the iPhone OS’s underlying architecture who will work with teams focusing on hardware, software and custom silicon. The ad says the employee will will work on “a range of hardware platforms, including iPhone and iPod”. That suggests that Apple is looking to bring the iPhone OS to more devices, and “the prime candidate would be the Apple TV,” according to the “Electricpig” tech site (http://www.electricpig.co.uk/2010/02/23/apple-to-use-iphone-os-on-other-platforms-–-apple-tv-next/).
