What kind of help do you require?
If it's a matter of information, I believe you'll find all the info you need on the subject here. Probably generating GGA sentences would be sufficient, but of course also looping through RMC and GLL should not hurt, either, and make it a bit more universal.
Maybe you should make the sentences generated and frequency of updates configurable?

I put some prints on the N900 python script, and I saw a message $PNOK from N95, I understand I need to answer this message with an OK, and so I did, and now the N95 says "Calculating GPS data" which is good! But after 10 seconds the N95 says "GPS does not work properly in closed buildings" or such line i don't remember it. The information I was trying to send is an example line of GGA in a loop, but it's not enough.

Well, did the GGA line include valid coordinates, what was it exactly? One thing might be that your GGA message included data indicating the GPS unit does not have accurate coordinates, ie. we might be indoors. How often did you print it? Have you considered also sending GPRMC, GPGSV, and GPGSA messages?
The NMEA standard itself doesn't really have negotiation, but PNOK is a proprietary Nokia extension which effectively does this. I suspect the N95 is trying to figure out if it is talking to a Nokia GPS unit or PSY?

Well I am trying to emulate an external gps not made by nokia, so I will drop the PNOK negotiation, and i'll focus more on message types. I'll see where this leads me. I am sending the messages every second, and the message was one i copied from a real gps fix from my external gps unit.

So, have you been able to make progress with this?
Or, are there more promising paths to take?
