I am new to the forum, but I haven't found anything on IAP and pp25/kuaiyong.
I have an iPhone 5 and and iPad both jailed, and unfortunately I can't jailbreak them because there is no jailbreak available. But when I found out about kuaiyong and pp25 I got really excited about being able to get free paid apps.
But the thing I want to know is if there is any way to crack IAP in a jailed device for the apps downloaded from pp25. For example The Walking Dead, the episodes are available as IAP so even if you download it from pp25 or kuaiyong you will only get the first episode, but you will have to pay for the rest.
More and more developers are using IAPs, which I think is pretty much like a scam. I check these stuff, but my dad for example sometimes buys an app and then finds out it's incomplete and that he has to spend another bunch of cash just to get to experience the "full" app.
