I have signed midlet (self-signed cert) and I have succesfully installed it into my 6600. Procedure to do that is
1. download midlet.cer from website by Opera
2. save midlet.cer and change it's trusted settings
3. install midlet.jad from website by Opera
4. change applilcation security settings
5. midlet is ready to use
Now problem is that model 6630 doesn't have Opera installed and it's own web browser doesn't regonize midlet.cer as a certificate file (Apache has AddType application/x-x509-ca-cert) but opens it as a text file. How I can install certificate over network without installing Opera?
