Minecraft Pocket Edition 0.7.0 Local Multiplayer?

Have someone create a new game. Then, with the device you want to join with, go to MCPE app, tap PLAY. Wait a moment(took less than 45 seconds for me) and you should see the name the person gave the world in BLUE(it will also say that it is a local game or whatever). It will be at the bottom of the list of your saved worlds(if you have any). Click on the world with BLUE text to enter the multiplayer world. Done!
