I have the new version I just got 0.8.0 and it's now a beta build I got it on the App Store. So when you join some one else's sever you can only place the item u have that is well its hard to explain if u see the picture I sent along u can old place the stone bricks and not any of the other like the ice. If u try to place it it becomes the stone brick. Please fix this mojang. Also update is awesome I will let you know if there are any more problems.
