I have found that my phone has stopped ringing (tone and vibrate) when it goes into locked mode. I tested it out today and it works fine when unlocked and dead when locked. It is set to lock when holstered.

I use the Profiles/Exceptions to create a whitelist of calls that I want to ring through (Quite profile standard with exceptions to a custom profile for the list I want to ring through). This has mostly worked fine until recently--mostly meaning that sometimes my list of people in the exception would be depopulated if I changed to another main profile)

Any ideas? This problem has been present since before updating to 4.2 OS.

Phone: Blackberry 8700c
