Nokia strange behaviour

Hi,

I have Nokia 6021 for almost one year. My cell several times change
itself bells without any reason. Reload helps and everything was exacly
as it should be, but now my Nokia made another joke - I can't clear
timers because my security code is wrong. Of course I typed right one,
but it doesn't work. I change phone language and tried to clear timers
again. Guess what? Everything works propertly. What's wrong with my
Nokia? Any ideas?

Aaah.. the same problem I have with my cell wallet - wallet code is
wrong, and I'm tired out.


Looking forward for some advices :-)


Best regards
