I've used iAP Cracker until it went down, and I was tempted to use this method. Instead I used iAP Free , which is almost exactly like iAP Cracker. It works with almost everything, except for server-dependent games such as The Simpsons Tapped Out.
Just to mention it as another alternative
Latest version of iAP Free (3.3) can be found from the BiteYourApple source ( it's an italian source, but it's kept up to date) :y:
