Deleted Calendar Information
While away from home, I was editing and deleting duplicate calendar items on the BB Storm. After 6 hours of work spread over 3 days the screen on the Storm became blank. After a few minutes, everything on the device calendar older than 1 week was deleted. Not only did I lose everything but I also lost 6 hrs of work.
I was able to restore the old information (but not my 6 hrs of work) when I returned home, but there is obviously some software bug that caused all calendar items to be deleted.
