Rockbox Ports are now being developed for various digital audio players!
I just tried with a 16 day old build on my iPod Nano and it worked fine. It also works fine after updating my nano to current SVN, and I've also just tried the 3.3 release and it paused on headphone removal too.It sounds like you may just have a faulty Nano.
1) I can't test this. I have no audio accessible by the OF and no software for syncing such. What the OF does is mostly irrelevant anyway. As I've said, it definitely works in Rockbox for me..2) Yes. It's the same hardware for headphone detection, so there was really no reason this case should be different than the simple "pause" case. But yeah, tested and works.
