Not much to say here.

A very basic tool that will import the N900 conversations to N9/N950.
I cooked it in a couple of hours.

The git repository is here: https://gitorious.org/n900-comhist-i...comhist-import

You can either build a package yourself or use the attached .deb here (The attached deb will only import text messages).

Please check the README file first: https://gitorious.org/n900-comhist-i.../master/README

I'm not interested in any farther development for it and cannot provide any support.

It worked for me for a few times BUT I'm not responsible if it screws up anything
