How to install root certificate on Windows Phone 7?

Just can not find how to install r开发者_JAVA百科oot certificate on Windows Phone 7. Does anyone know?

Apparently:

You can do this by emailing the RootCA to the user of the phone. They click
on the attachement and it will prompt them to ask if they want to install
the certificate on the phone.

I've not tried this though and so can't say for sure if it works.

As there is no way to install a cert programatically I'd look to use a cert from a source which is already trusted by the phone instead.

I wanted to use CharlesProxy on Windows Phone. What I did was the following:

1. Go to charlesproxy.com/charles.crt (file will be downloaded)
2. Save file as .cer instead of .crt
3. E-mail file to an e-mail account that can be openen with an e-mail application on WP (somehow you can't download e-mail attachments using a webbrowser on WP)
4. Click on attachment (once for download, twice for installing)
5. Have fun proxying.
