Here's a quote (http://www.pdastreet.com/articles/2...-How-to-Do.html
) from How to Do Everything with Your BlackBerry by Curt Simmons :
"When memory begins to run low, the BlackBerry has to make room for new, incoming messages. To find the room it needs, the BlackBerry begins deleting the oldest messages in the Messages folder; however, messages stored in your Saved Messages folder are not deleted. In order to avoid the potential message loss, it is important that you keep your Messages folder tidy—delete messages you don’t want and save messages that you do want. These housekeeping actions will help ensure that you do not lose e-mail that you might need."
By resetting the device, you can reclaim some of the memory your programs didn't release properly. That makes it less likely the BlackBerry would have to force-delete any more messages--at least for awhile.
