HTC is one of the best designer in the Windows Mobile world with their sexy headsets, but the functions that come with these things are not as great. This tweak created by an XDA member attempts to fix this issue. The tweak, which is very old changes what happens when you press the call button on your headset. here is exactly how it works “one long press on the headset’s microphone button => play/pause press quickly two times => play next track.†The tweak was confirmed for the HD, but I can not personally test this due to my headset being broken and cannot find another. Give this tweak a go and give us a comment on how it works out for you.
