I found away to get unlimited gold.
you do need to be jailbroken.
step one — download a memory injector GameGem/IGG or any other memory injector will work.
step 2 — go to a shop then proceeds to where you can buy something.
step 3 — set it to where you can buy 50 of an item and use your memory injector to search “50”
Step 4 — switch the amount of what you want to buy to a quantity of 10 (if you need to keep serching between “50” and “10” then do it till there is only 2 or 3 results.
step 5 — set the quantity of what you want to buy to a negative number for example “-10000”
it will buy a negative amount of that item and In return you will spend a negitive amount of money on item which will give you tons of gold to spend on anything you want.
hope this helps
