I don't know if Net. CF would help much. But if you look under settings>system>certificates there's a personal section there maybe your tech could import the needed certificate.
I've noticed that Netfront 34 beta 009 (still free) under menu>tools>security setting. There's a certificate manager that allows the importing of certificates from a storage card maybe the tech. could extract the cert. and save it to a storage card and import it using Netfront 34.
Edit: Here's the link to netfront.
