Is there a calculator program available for the N80?

Yes. It ships with the Phone. Its called Calculator. Not sure which folder its in though.

Have had a look on the phone and the manual and can find no mention of a calendar, any more clues?

Neil

There's certainly a Calendar in the N80, normally accessed from the front screen!
My Calculator, on the other hand, is located in the OFFICE folder, along with the unit converter, quick office, notepad and sound recorder.

Many thanks found it in the offfice folder, strange place?

Neil

Yes perhap so. Maybe they think you onyl add things up in the Office?
