I've been having trouble using in-app purchases on my jailbroken iPhone running iOS 4.1. I keep getting an error...something about sandboxing. Most places I looked online said it was related to using AppSync and cracked apps, which I did try at one point, but I deleted all the cracked apps and uninstalled AppSync, etc. I logged out of my apple account and loggrd in again, deleted the app, restarted my phone...still, doesn't work. I know you don't condone piracy here, but I am not pirating. I deleted my cracked apps quite a while ago, and am now dealing with the consequences of having done it in the first place. Any ideas?
