Default points of contact

thanks you have confirmed it will support atleast three points of contact. To support volume control it needs four points of contact if you remove the headphones from the phone and look into the socket in the phone you may have to put it near good light you will see atleast 3 layers (at different depths in the socket) of metal contacts, are there 3 or 4 sets of contact points? if there are 4 it will support volume control. Please post your answer if you could.

additional info

this link sums it up aptly in paragraph 3
4 point contact = compatible models
3 point contact = unlisted devices
2 point contact = standard devices

it needs the jack (hardware) and software support to work though.
I would still like to know if this phone supports 4 point contacts.
