"Double-pressing the power button does lock the phone.."

then y would i want to tweak it?!?! i want it to lock AND unlock it pressing it once each time!!! and not using the slider on the headphone side, or doin the swipe thing! JUST SIMPLY ONE POWER BUTTON CLICK = LOCK, ONE MORE POWER BUTTON = UNLOCK... EXACTLY LIKE USING THE HEADPHONE SIDE SLIDER DOES EXCEP USING THE POWER BUTTON INSTEAD! [ like on htc ]
