Forum:COD: WaW Zombies help

Intro
I'm planning to get an app called Call of Duty: ZOMBIES for Christmas, mostly because I want to play zombies again after I've stopped playing BO2 zombies (think it'd had something to do with my month-old seizure) & I always wanted to play the four original zombies levels; if you don't know what they are, consult to the list below to find out:

List of Levels

 * Nacht der Untoten - Night of The Undead
 * Verrückt - Crazy or Insane
 * Shi No Numa - Swamp of The Dead
 * Der Riese - The Giant

Problem
Basically my problem was: Does the IPad version of the game JUST have the first two levels above, or the app does have all four levels and the last two are DLCs? Or if they're not then I'll just get the iPod version

Conclusion
In the main, please answer my question above. I don't care how you do it, but I recommend via comment or send me a message.
