I have eventually managed to get my modded codes into app nana. App nana is a free app that gives the user free nanas by purchasing paid or free games, these nanas will enable the user to purchase iTunes vouchers etc. This code will give users 25,000 but you will need 15,000 nanas to do it. The code is s1815756

Also this code will get you free premium gold packs every week without paying for them.
