How can I mine redstone ore?

I found redstone ore in Survival Mode (Minecraft Pocket Edition) and tried to use all five tools to collect it. It took about a minute or two to break, but I couldn't collect anything from it once broken.

How do I mine redstone ore?

Solution 1:

According to the Minecraft wiki, it's currently impossible to mine as of version 0.7.1. It can only be destroyed.

Since 0.8.0 build 2, you can now obtain redstone by mining redstone ore with an iron or diamond pickaxe like a normal ore.

Solution 2:

It is currently impossible to mine redstone ore in Minecraft PE. Just wait until a new update comes out!
