Notices

I want to make program that generates "fake" incoming sms, so I get custom Message from custom number to Converstaions.

I have been looking at d-bus signals and methods, also sniffing with mdbus2, no luck so far.

Is this even possible?

I believe that what you are asking is not legal. I suggest the administrators to inform the police authorities of your country to make some investigations on your intentions.

Actually, it doesn't have to do with legalities, at all, you're doing it all locally.
Have a look at sqlite3 and ~/.rtcom-eventlogger/el-v1.db

What he does to the conversations on his phone is perfectly legal (I assume in any country.)

Is it strange? Yes.

Illegal? No.

MohammadAG, above, has the answer for you. All of the sms messages are stored in the eventlogger database on the phone. There's nothing to stop you writing your own messages to the same db, which can then show up in conversations as any other message would. In basic terms, all you need is a simple app to gather your text message into a text field and use a SQL statement to write it to the correct eventlogger database tables. Perhaps even simpler, you could execute the SQL statements containing whatever fake info you'd like to the database directly from xterm.

thanks, doing it via sqllite is way to go for me.

i have a feeling this is about trickery of a "loved" one...

As long as it's not used as evidence in court, I guess...

more likely former loved and now hated. oh theres so much evil could be achieved this way i'm feeling dirty jus thinkin about it!

You should probably use the rtcom-eventlogger API, which would be cleaner than writing to the database directly with sqlite (for example, might not break with system updates if Nokia rename the .db file again, as they did previously). See http://maemo.org/api_refs/5.0/5.0-final/eventlogger/ or search for "rtcom-eventlogger".
