I made this simple program for who want to save message in SD... The usage is very simple, you dont need any manual for that... Install the program and set to root (important!), then when you select it in the first time, it will copy all of your message to SD (/mmc/mmca1/.system/sysDatabase), and make a link to sysDatabase in both ezx_user and ezx_local, the original sysDatabase will rename to sysDatabase2... So you can choose both phone and SD as your message storage easily and no data will lose... The change will be applied after reboot...
