iOS 6 devices don't work

if you want to make the test yourself:
1. Download iExplorer
2. Go to Browse Backup
3. Go to the Minecraft app
4. You will see that only Documents and Library folders are supported in changing

This means that pictures, code in the other folder are sandboxed (this is preventing hacks into the game, stealing textures)
It does work with jailbreak (test confirmed) elsewise NO
It is the way USB Tunneling works
