One of the issues with the BlackBerry Storm is that the touchscreen stays active when you are on a call and it is not terribly difficult to inadvertently activate applications while the screen is pressed to your face.

I personally use a Bluetooth headset almost all of the time and personally have never done this, or, at least have never noticed that I’ve done it.  It is however, a big enough issue that the folks over at CellAvant have created a free BlackBerry application, TalkLock™, that sovles the problem.

TalkLock™ is a free utility that automatically engages a few seconds after a call is connected, and intercepts touch screen actions. This prevents screen presses from launching programs or invoking functions while you talk.

I just downloaded and installed TalkLock™.  It seems to work thus pretty well thus far.
