Well, 0.3.2 is out. Smelting HAS been added, and with that, the ability to mine Lapis Lazuli, Gold, Iron, and best of all, DIAMONDS! (If you want a seed with diamonds directly under your spawnpoint, pm me!) However, redstone cannot be obtained as of 0.3.2. If you try to mine it, it simply breaks. So, just leave the redstone until the next update is out. It might be obtainable then! Hope this helped.
