you are wrong. the phone uses the id pin to tell what mode it is in. a different resistor on the pin means different modes. there is a USB mode, a UART mode and an Analog mode. If the phone isnt programed to recognize the different modes, it wont work. phones that dont have an external headset jack are programmed to switch between USB mode and Analog mode.
