Default Shure Music Phone Adapter (MPA) and Hero

Is anyone able to comment on whether the Shure Music Phone Adapter (MPA) accessory works with the GSM Hero? I suspect it does but it's a bit too expensive to chance it. Links at http://www.shure.co.uk/PersonalAudio...pa_MPA_content and http://www.engadget.com/2008/09/02/s...tereo-headset/

Thanks
