Not sure if this will still help you as your post is kind of old, but I just signed up today, so it's not my fault.
😉
And I can't resist answering a question that no one else could as my first post even if you're long gone.
I'm not sure if that is something that PC Suite is capable of at the moment (I don't run anything M$).
Now, this can still be done, but it depends on how comfortable you are with Linux.
To just dump them to a text file, do the following:
Open xterm (you don't need root) and enter the following command (note: case matters. a <> A in linux)
Code:
~ $ sqlite3 .rtcom-eventlogger/el.db "select * from events where event_type_id in (7,8) order by id;" > /home/user/MyDocs/sms_dump.txt
This will create sms_dump.txt which will contain all of your inbound (type 7) and outbound (type 8) SMS records in chronological order. You can also export the other types contained in the table, just add them to the sqlite3 command above in the brackets separated by comas.
Here is the list of the types:
1 = inbound call
2 = outbound call
3 = missed call
4 = voicemail message
5 = inbound IM (integrated conversations only)
6 = outbound IM (integrated conversations only)
7 = inbound SMS
8 = outbound SMS
When you've run what you need to run, plug the N900 into your PC in mass storage mode and you should see the file there.
You can import it with Open Office Spreadsheet or Excel if you are using M$ (boo you in that case).
Also, best place for help with the N900 is talk.maemo.org
Enjoy.
