Oh, another thing, anyone here had any luck installing a Class B certificate?

I work for HP and the majority of external facing websites etc (sharpoint for example) require me to have this certificate installed.

There is a WM 6x installer, but as its in a cab it doesnt work.

So, then I tried extracting the certificate from another WM device, and emailing it to WP7 - it says it worked, but still wont authenticate.

I know its possible, as if you email the cert to an iPhone, it works.

Any ideas?
