unity iphone: certificate and itouch pairing

I've been trying to get the certificates correct with the profile and pairing my itouch so i can develop on it but I keep getting an error. Is there a proper tutorial on how to do this? I've found one but he leaves out a lot of steps.

The "how to" tabs for certificates and profiles in the provisioning portal in the iPhone dev center at developer.apple.com tell you everything.
