Does anyone know what function each of the wires has in a Samsung SGH-T139 data cable?
the cable I'm talking about is part of the hands free set.
twisted pair of dark bare wire around an insulated purple wire
Its better if you test the wires back to a connector (hence this site) as cables like these may not retain the colors in all runns of the cable. I've personally destroyed Devices when one cable and another had the same Colors (internal conductors) but pinned them out differently.
Then ask "what does pin 1 and pin 2 do?"
