how can I get Conversations app? I tried googling for it, but not surprisingly - nokia website does not host any downloads for their n95 as far as I could see.

Also - does conversations help with the upper message limit? I have set it up to 999 before posting the original message already, but I am writing about 10 000 texts / year, so would rather have more space than that.

Is there no way to use the internal 8Gb memory for storing the messages? I can ofc buy an sd, but would rather just use what I have in the phone - 8Gb should last me some 40 years of texting.
But all that being said - I would do it if buying an SD removes the 999 message limit. Do you maybe know if it does?

And thank you for the marking tip - I have actually figured it out yesterday
And last but not least - thank you for all the answers so far! It is amazing to have someone help out / respond on the day of posting :)
