of course the real question jyazzie110 was answered in post #2, only thing he/she was originally asking can only be 100% confirmed by an "insider". From my experience post #2 is correct even though I'm not a true "insider".
Oh forgot to add, I can tell you this much. Your carrier has to purchase the codes in blocks from the manufacture vendor, which is why a lot of times the carriers will not have the codes for several months and be telling the truth. They are lying to you in the standpoint "the codes aren't available yet from the manufacturer", the reality is they have not PURCHASED them yet. Its a completely convoluted system that I believe just subsidizes the manufacturers.
