By default when you plug your headphones into your iPhone, iPod Touch or iPad your music does not begin playing where it left off. With the Plugication Cydia tweak however that was just released into Cydia today, this all changes. What the Plugication Cydia tweak does is forces the Music.app to resume your music playback when you plug your headphones back into your iPhone, iPod Touch or iPad.
