I received my new Bose MIE2 mobile headset. Anyone have any idea how to gain control over the button? I'd like to use it to mute/unmute while I'm on a call. It seems to end a call instead. I tried various headset button controller apps in the market but they all seem to fail taking control of the button despite their debug mode showing they are interpreting the button press (any idea what setting is retaining control over the function)? Thanks!
