I did all the steps and I’m able to transfer the cracked app to itunes. After i have the cracked app in itunes i then plug in my iphone that isn’t hacked. I then try to sync everything to the iphone. When the sync progress is complete it gives me that error 0xE8008001 again. What’s the problem?

@gbaseball:

apparently you need to reboot the phone after installing AppSync, then make sure that you download at least one app from the appstore (can be free, can be paid, your choice). Then it should work. hopefully.
