i bought an htc e100 rc headset and all was well for a week but all of a sudden the headset has stopped working. Before the little headset icon came up on the top of the screen. now when i insert the headset into the usb nothing happens. The normal 3.5mm headphone jack works ok but i'm missing my buttons for next and answer call and stuff I found a way of slowly pulling out a headset from the 3.5mm jack which allows me to get the e100 working ish. Basically the audio can be heard using it but the buttons dont work. Anyone got any ideas??
