If iPod app doesn't start, then my theory about headphone jack is
wrong. Your category can't keep that from happening (iPod will assert
its own category).
Can you write a bug at bugreporter.apple.com, please? I'd like to
track this down.
Thanks!

There is a strange and fairly rare bug where pulling the headset
jack at _just_ the right speed causes a transient "hit" on the jack
connector in such a way that the driver thinks an Apple headset's
"Play" button has been pressed. So the iPod app starts to play a
song, and your app gets interrupted.
Is that what's happening?
The iPod app doesn't start playing, but that could be because our
app is set up as a "play and record" category.
Another thing to note: we are able to replicate this issue here
every time. This could be because we pull out the jack at the same
speed or at the same angle, but it never came without a failure.
