Hello,
I have tried installing a client X.509 certificate on my N95 and the phone prompted me to create a password for some kind of a security module (I believe at least, wasn't paying too much attention and can't reproduce it now). I entered a passphrase but I started getting "Security module error" errors and I couldn't find my client certificate under Tools->Settings->General->Security->Cert. Management - Personal tab. What's worse, now my phone gives me the "Security module error" every time I enter Tools->Setting and if I try to import the certificate again I get "Unable to save file content" error. (Importing and manageing authority certificates still works.)
Any help would be much appreciated as I need this functionality to connect to network.
Best regards
