How to change values in apps?

Hello everyone, I am a low level programmer and I had the question, how to changes values in apps?

For example: I am playing a game on my iphone and the purpose of the game is to kill the zombies and when you kill a zombie you get a coin. You can you coins to but weapons to kill more zombies. Now I just want to give myself coins without killing zombies, I know it is possible but I only have seen it in a jailbroken iphone, I know it would be easier if it was an android, I had an idea to connect it to my computer in itunes to see the code and change it but I'm unsure, can someone help me?

Thanks

Basically, you need Jailbroken IOS device and some cracking software like Game Gem and that's it. You can find a bunch of tutorials on yt.

1 more thing, I never had a successful jailbreak before, people do if for me so i need help

Be aware of any security issue of updating a file that will most probably be located in Program Files. Under Vista, you need elevated permission to write to a file in Program Files.

You can download some hacks for that zombie game. There are plenty of hacks or cheats you just have to download it from the internet and connect in your phone. You can also visit youtube for more tutorials and cheats about your game

Enjoy Play nice
