Serving notice forms in court never delivered?

I recently got stopped for speeding and didn't have proper tags/plates because we just moved to California. I received my ticket, but since i'm under 18 the officer said "since you;re a juvenile i'm not required to have you sign the ticket, i just have to have you verbally agree you're getting it, and i'll notify you in the mail with your court date" Now in the mail i received form jv-625 and it has some court info, but according to some other sites i need to get served with sc-100 or sc-120. yesterday a lady from court called and said if i could go down to sign some paperwork (my papers for me to be served) because she didn't have time to come to my small town. Court is tomorrow and technically i never got "served". Will the court consider the jv-625 form a served notice? It came in the mail unsigned and unstamped by anybody from the courts. Even if it was signed and stamped would that count in the court of law?
