Been battling this phone all day.. won't let me sync

'the security certificate on the server is not valid. contact your exchange server admin or isp to install a valid cert on the server support code 0x80072f06'

I have installed activesync on my computer, exported the cert's from my browser and copied them to the phone via activesync. Then on the phone, opened the certs, they say they install correctly.. still having issues. My certs are self-signed. Is there a way to fix this with a self-signed cert or do I need to hit up godaddy or something?

I notice theres two certs, one is "Intenet Widgits Pty Ltd" and the other is "DataSync Web Admin"
