Is there an alternative calendar application to the one that comes with the communicator and is it possible to map the Calendar key to this or any other program?

HI

I have been trying to find one myself, but with no luck. There is an app call agenda4us, see http://www.allaboutsymbian.com/software/directory/viewsoft.php?id=282
but that's about it. I once tried to install a midlet called Calendar, but it didn't work.

BTW Does any of you know if it is possible to have two separate calendar-files on 9210?
