I have found the the keyguard does not disable all calls, it still lets the phone dial 3 digit emergency type numbers. I found that out when I got a call from a 911 operator saying my phone had been calling and hanging up. My keyguard was still on, so I I tried it and yes, with the keypad locked it still dials. Wasnt the point of a keyguard to stop accidental 911 calls ?

So, how do you make the keyguard actually useful and set it to disable all calls when locked ? I have only had this phone 2 days and if I cant stop it from doing this I cant keep using it.
