Hello all!

First of all, this "Cheat" requires NO JAILBREAK

In this post I'm going to show you how to create a creative world in Minecraft PE and then change it to survival, with all the changes you made there remaining!
It's very easy to do if you have the appropiated tools:

-Minecraft PE (Free with PP25 or 5.99$)
-iFunbox/iFile/iExplorer (iFile does require JB)
-5 minutes
-Some intelligence (brain required)

Let's start now!

1. The first thing you have to do is creating a 'Creative World' in Minecraft.
2. Place everything you'd like to have in Survival mode (diamonds, tnt...)
3. CLOSE THE GAME EVEN FROM MULTITASKING
4. Now, go to iFunbox and look for /Minecraft PE/Documents/games/com.mojang/minecraftWorlds.
5. Open the file with the same name you made some minutes ago.
6. Delete the 'level.dat' file.
7. Now create a normal survival world named 'abcd'.
8. Play it for a second and close the game.
9. Go to Minecraft PE/Documents/games/com.mojang/minecraftWorlds.
10. Copy the level.dat file from abcd(the survival world)
11. Paste the level.dat into the Creative world you made.
12. Refresh.
13. Done! Now open the game and see the creative world is now survival!

Enjoy your game!
