[Centos] 4beta gpg key

Hi,

Maybe a stupid question:

I just installed centos 4beta on a Dell inspiron 3500 laptop.
So far so good. But where do I find the gpg key?

Transaction Listing:
  Update: firefox.i386 0:1.0-6.centos4.2
Is this ok [y/N]: y
Downloading Packages:
warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 4fe06303
public key not available for
//var/cache/yum/update/packages/firefox-1.0-6.centos4.2.i386.rpm

I imported the c3 key, but 4fe06303 seems to be another.

Regards,
