The reason why you web service call fails, is because of the fact that "the
certificate name doesn't match the server name".
This is true for desktop web service calls as well. If you use IE, pocket or
desktop, and it comes back with that message, you will not be able to call
web services on that server using SSL.

The reason why "the certificate name doesn't match the server name", is what
it says. If your computer is www.mywebsite.com, then your certificate must
be made out to www.mywebsite.com as well. I'm not sure if this can be
achieved by generating your own test certificates for your test server, but
ask on the IIS newsgroups.
