I have also had similar crashing issues recently (on stock JVQ with KC1/KG3 modem, rooted)
I had thought it may have been a launcher issue, but no, I have had the issue occur with different launchers. Also, lately I have had dropped calls....regardless of signal strength or whether I dial out or pick up a call. Both are getting to be annoying.
edit: also forgot to add that I have crashed to home screen after entering the dialer and pressing a few numbers (not actually completing the entire phone number; around 4 digits usually).
