I'm not sure but I'm 100% sure that you need to jailbreak to get the mods Apple is too stupid and annoying and strict + everything in the world to allow it. All I know is Apple is the worst company ever I wonder why I'm switching to android Apple won't allow mods for years to come.
I used signaturecraft.us to get my signauture it's a Minecraft signature maker. Also you can transfer you iOS world to Android although it requires a PC to do so. You need jailbreak also I'm not exactly sure how to do it but I do know iFunBox is required to take the world off of the iOS device then you need some other programs to transfer it to android as of now I'm not quite sure.
