Is it possible to install a certificate on a Nokia S40 device (e.g. 6103)? I have tried everything that I've read on the internet after many hours of searching forums and Google'ing.
I exported the certificate from IE, saving it as a cer file in DER format. I transferred this file to the phone by dropping it on the OBEX file transfer link when connected via IR - the phone did not recognize it and stored it as a .cer.txt file. I then configured a web server to download the file from the phone's browser with content type application/x-x509-ca-cert. This killed my phone - it won't boot up now, so I'll have to send it in to be re-flashed.
The phone seems to support user certificates - it's a menu item in the Web menu. How are the certificates supposed to get on the phone?
