It's been happening for me. As well as reboot loops, where it kept rebooting even after hard reset and battery pull. Only thing that seemed to stop it was sliding out the keyboard (or was just coincidence.)
Also losing connection to the VZW network in places my Storm works.
Happened to me for the first time a short while ago. Two things that were happening at that time - no idea if either is related:
1. Sort started to open my keyboard and then closed it
2. battery had just about hit the magic 30% number where power manager switches to a low power profile.
I could be wrong, but I read on another forum that most of the apps in the apps store were designed originally for the original Android OS. It could be possible some apps cause conflicts with 2.0 and causing this to happen?
