Skyz, no time no see.

I jb ipod touch 2g. First use greenpoison. After jb, no loader icon, then I just redsnow to add cydia. It's okay with icon of cydia nd loader. Then I follow the steps to activate cydia. After upgrade essential and restarted, the cydia and loader icons became white, and when i enter cydia, it gave message "Unable to Load(the certificate for this server is invalid. You might be connecting to a server that is pretending to be "cydia.saurik.com" which could put your confidential information at risk.) I restart the ipod and still the same.

What should I do.

Thanks.
