So the crashing has been happening again; about once a day.  I think I’ve isolated the problem to Pocket Informant 8.  I’ve removed the software and it works fine now.

I’m using Agenda One to do my stuff now, and my phone seems happier.

Update teh 2nd: I turned the auto update feature for Agenda One to check every day, and lo and behold, my phone had crashed in the middle of the night (but also rebooted on its own, so it’s not so bad) so it looks like it’s not limited to PI8…any app that tries to open the Data connection when the phone is asleep and locked with a simple PIN type password.  So I’m back to looking into this issue.
