Hi, Yes, reformatting the phone would not lose the firmware, that is there for ever, once you have updated. I would go ahead and reformat the phone if I were you.

Can I reset/format the phone memory without undoing the last firmware update ( firmware is using most recent) 3. would the Nokia system take up 28 mb of the available 46mb? seems a lot to me. any thoughts would be good Alistair !
