No worries! Also searching for "iphone call recording" on your marketplace of choice like amazon, also shows many results including usb dongles which act as a bluetooth dongle as far as I understand. I neither own an iPhone nor any of these devices, so I can't tell how usable all these devices are! Probably a middle man bluetooth device which you would connect via bluetooth from the iPhone, which then connects to a bluetooth headset could add a noticable delay, but I haven't seen such a device (maybe because of that exact reason)
