Anyone know of a keyguard that only works for PHONE functions? In other words: the normal Treo keyguard requires me to press the center button to turn on the PDA for ANY reason. I don't really care so much if the PDA turns on in my pocket (sure I will lose battery, but not a disaster), but I DO care if my phone dials a call for 600 minutes because I don't notice it's on.

So, anyone know of a keyguard that only requests a confirmation when the dial function is called, but doesn't ask for confirmation when the PDA is jus turned on?
