AutoMsg sends message automatically at set time. I will issuing an update for a the current version and a special version for Symbian phones soon. Till then keep checking.

Note (for Nokia 6230i users): N6230i has a bug in its Java platform.
The bug is that if you are using 12-hour mode like 12:34:56 pm then all java applications will show just 12:34:56 am and not PM.
This bug is there in all N6230i phones (I myself use N6230i ;-) ). The solution is to switch the system clock to 24-hour mode from 12-hour mode in the Time & Date settings menu.
