Quick tip: Volume buttons awaken HTC EVO 4G
While many people have happily left the Apple ecosystem for the HTC EVO 4G, some still miss being able to awaken the iPhone with one of two buttons: the power button at the top and the home button below the screen. Having to press the EVO's power button to awaken it isn't a problem, but since the button is more recessed than many people would like it to be, it can sometimes be a bit cumbersome. Its placement on the top right has occasionally tripped up some folks as well.
But while the EVO doesn't have a hardware home button, it does have a volume rocker. And unlike on the iPhone, pressing the volume up or down button on the EVO does awaken the device from standby if you've disabled the lock screen. It does it without adjusting the volume, too, so you don't have to worry about having to readjust it later.
So to all you former iPhone users out there, don't spend another second wishing the EVO had two buttons that could be used to awaken it. It already does. And if you count the volume rocker as two separate buttons, then it actually has three!
