most of these seeds are probably on the infinite world setting which works on Apple or android. the problem is that the ipod 4 has a hard time running infinite worlds. I think you can still run an infinite world without too much lag, as long as it's multiplayer and it's not one of your worlds. Also I don't know if villages spawn on the old world type but village seeds that work on infinite probably won't work on the old world setting (I tried a couple).
Seed: Notch ; its 5 villages, few zombie spawn caves & an abandoned mineshaft (so far). Found it while putting in all the creators names in different ways. Some are cool & do spawn villages but this is the best. Go straight/right for a mountain village. 4 villages are close but the dessert village is far. If you dont want to explore.... in the mountain village library dig straight down & you should eventually get to the mineshaft. While searching for more I got lost so let me know if you find more.
