In Minecraft PE there is a Problem relating to Worldgeneration: I've been trying for ages to find a Seed in wich you can find all Biomes, but i never managed to find one - I didnt manage to find all Biomes in any of my Worlds (other than in PC edition, where you find each Biome in any World) This is a serious Problem if you need e.g. Packed Ice in Survival Minecraft because you are never going to get access to it. I personally think there needs to be done something about.
