you may need to restore the software. Sometimes (rarely) the jailbreak doesnt take right, and you get no service. Follow the tutorials at hackthatphone.com to restore/jailbreak/unlock it again. Unless any one else has any other ideas.

Thanks kelly, found out the phone was jail-broke but not unlocked!
