Well, that's quite simple and it works. I have no idea why I didn't think of running script as root, I just thought that bluetooth port numeration has nothing to do with unix/linux overall port numeration... stupid me :P

Thank you very much.

Now, I have a working setup:
Nokia N900

Code:

import bluetooth

server_sock=bluetooth.BluetoothSocket( bluetooth.RFCOMM )

port = 3
server_sock.bind(("",port))
server_sock.listen(1)
print "listening on port %d" % port

uuid = "A55665EE-9F91-4610-9085-C2055C888B39"
bluetooth.advertise_service( server_sock, "btsppEcho", uuid )

print "Waiting for connections"

client_sock,address = server_sock.accept()
print "Accepted connection from ",address

while True:
    data = client_sock.recv(1024)
    print "received [%s]" % data

client_sock.close()
server_sock.close()

And final connection string in MIDlet is:

Code:

"btspp://" + myRemoteDevice.getBluetoothAddress() + ":3;authenticate=true;encrypt=true;master=false";

Thank you once again, you saved existance of my app
