This KB<http://support.microsoft.com/kb/915840> worked for WM5, but I don't think it'll work for WM6 or 7. Basically, because the certificate store is accessible only to an app built by your phone provider, it's them you have to work with.

On the company we are migrating from BB to Windows Phone 7. That means, a couple of applications that are running on the BBs needs to now run on WP7. The application with issues is making a HTTPS call to a website (if you access the website from IE works fine). But the application basically is ending the connection because of an untrusted certificate (we use COMODO certificates for public sites). I was told, the apps part of WP7 only check if the root certificate of the cert used on the site is on the trusted list. But if there is any intermediate certificate, then the ISA or whatever is publishing the site needs to be provided. From my limited knowledge of the product, that is not doable and is also not secure. But I can be wrong of course. Can anybody tell me if that is possible and if it is, how I can offer an intermediate certificate on a web site published with ISA 2006? Thanks in advance Regards Diego R. Pietruszka
