i dont know why but when i get a missed call, it will not show who or what is calling me on logs menu also recieved calls and dialled calls.. its just (no missed calls) i just noticed this yesterday and i dont think ive done no settings change or whatever, does anyone know how to fix this prob.??

In the "Log" app, Options > Settings, what's the "Log duration" value set to? Even if it is set to something (1 day, 10 days, whatever), change the value to something else & see if it helps.

it was set to 30 days on the log duaration so now its set to 1 day. it was ok when i first bought it, it showed who dialled, who missed called, & recieve calls and now it showing nothing:con?

-Try to remove ur MMC and try it again.
-Try to run phone with safe mode (hold the pen/pencil key while booting) with/without MMC
-Format ur phone/MMC: http://www.allaboutsymbian.com/forum/showthread.php?t=44365
