Jeah, thanks a lot! :-) I guess I have to learn more about Linux and C++ programming to make a aplication running directly on the N900. :-/ It's not done by editing a XML File vom outside. telepathy Protocol (see File Formats and Tutorial) I'll see... Windows and .NET is not the answer of all questions! And with MONO it will be possible to write applications accessing the whole telepathy API in 2012. ;-) I need more time in my life! Mmmh... ooookay. I'm finished with a application to import text based SMS messages in the N900 system Summer 2011.
