I need "better" calendar/planner

[forumer9]

I have Nokia 5230 and its calendar is not bad at all, but there is one simple function that is missing.

Heres what I need:

I create new meeting that will happen friday between 16h and 20h. Next day I try to create new meeting that will be on that same friday but it will start at 17h. I would like that software then informs me that I already have meeting at that same time.
I know that I can see that by myself if I go to that day....but this eay it is easier for me...

Is there any application that has that function?

Thanks!

You can try creating meetings in outlook. There you will get such alerts and then sync with your phone.
