  • Jailbroken iPhone doesn't unlock? My friend's Iphone locked and doesn't unlock now. He enters his password but it still doesn't unlock. And also his iPhone is jailbroken. He installed localapstore (a cydia tweak that allows to hack in app purchases). He only once hacked a game. I just say this because I think this could be the reason. Maybe apple blocked his iPhone? And also we tried to restore, but it doesn't do anything. So what is the solution to the problem? How can he unlock it?
