Actively considering using Digicert here so your info is appreciated. We can work around the primary domain not matching because our landing page has no real need for SSL, however, we do very much need iPhone support on the subdomains. Would you happen to know if Digicert Wildcard SSL certs work on the iPhone? Thanks
