I want to get a headset to use on my Razr Maxx, but I've been trying without success to determine if my phone accepts the 4 connector plug that comes with the headset or just a regular stereo plug? I can't find that in the specs anywhere and even if it does accept it, are the pin outs going to be the same? I think I can work around the latter issue with an app, but if it physically doesn't have that fourth connector, it won't work.
