minecraft has a copy on the appstore wich is at survval beta and working multiplayer!
its called minebuilder and costs £1.50 its probably even better than acctual minecraft because its no furnace time just instant and i find it all epic i just like it as well plz give this diamond so other ppl can see and why not get it and go to the minebuilder fourums so if ur using android u can change the texture pack currently he is working on texture packs for the ipod.
