Apple is looking to hire a full time engineering manager to help bring iPhone OS to new platforms.
From the Job description:
The Core Platform team within Apple’s Core OS organization is looking for a talented and inspired manager to lead a team focused on bring-up of iPhone OS on new platforms.
My first guess would be an iPod nano-like device using a modified version of iPhone OS. I’m obviously pulling that out of thin air but I wouldn’t be surprised if Apple wanted to simplify development of their mobile devices by running the same OS on all of them.
