Yes you can but you need to mine it with an iron pickaxe
Either diamonds are not fully implemented yet in Minecraft PE, or you used the wrong tool, you need an Iron Pickaxe at least.
You can break the block with an iron pickaxe but not gain the drops. Not sure why they added the ores but not the actual redstone. I suggest not mining it so in the future when they add redstone, you have the ores to mine.
with an iron, gold, or diamond pickaxe (there isn't any uses for redstone in pocket edition so you won't get anything
you dont but anything that requires steel just use iron ingots put the ore in a smelter and BAM! there you go.
To obtain the drop from iron ore, you will need a stone pickaxe or better. Any tool/item can break the ore but it won't drop anything unless you use a stone or better pick.
