I'm new to this forum, so I'm sorry if this has been discussed before, or if it comes off as a novice question. I was wondering if there is an app for a jailbroken iPhone that allows you to designate which application the headphone mic button controls. I don't even know if such a thing is possible, but I use Simplify Media instead of the iPod app to listen to music on my iPhone, paired with the backgrounder app so that I can keep it in my pocket with the screen off and still listen to music. The only thing missing is that it can't be controlled with the button on the headphones. If it could be reconfigured to an application of my choice, it would make listening to music that much more convenient. So far as I know there are no apps out there that integrate the headphones in this way, so I'm thinking it's kind of impossible, but I'd like to make sure. Does anybody know any reason why this can't be done?
