PS3 Call Of Duty Black Ops Zombie Mode Maps

[dazp]

Hi people

I have brought black Ops (last night) the standard game as I could not get the hardened or prestige packs and I have notice I can only play 1 zombie map, however looking around there are 7 maps in total but 4 of them are for the hardened or prestige packs. Now are these maps going to be set up on the playstation store to down load or do I have to buy 1 of the packs or get some nice person to pass on the codes to me?
I understand there is a cheat code I can do to get two maps or complete the game and it will unlock these games.
The list below is what I beleive is the correct maps (taken from http://www.cheatmasters.com/cheats/33040/Call_of_D... ) , could some one correct me if I am wrong?
