I have a Curve 8310. That will constantly wipeout all my text messages and call log, but leave my emails. It is doing it so regular, i'm so ready to throw this thing out the window... Has anyone heard of this and is there a cure??? I love my crackberry, just cant live with this problem.....

Check your free memory: Options / Status / File Free:

What you are describing is typical of the problems caused by low available memory. Any time "File Free" drops below about 12 000 000 bytes, the phone may start deleting call logs and text messages without warning to free up memory. Text messages may be deleted as soon as they arrive, before you have had time to read them.

A battery pull recovers memory and will alleviate the problem temporarily. The solution is to remove the stuff you don't need (the sample video, wallpaper, themes, other languages, brickbreaker, etc.) from the device's memory. The following procedure, originally written by Forums Moderator Reed McLay will guide you:

Also, if you have a Media Card, be sure to put pictures, videos, music, and ringtones on it, not in your device's memory. Keep in mind that Media Card memory is not device memory. You have to keep your device memory above 12 000 000 bytes, regardless of the capacity of your Media Card or how much free space it has. Finally, you can't at this time run programs from a Media Card. Programs have to be installed in and executed in device memory.
