Group 3: Stupid people. These are the people that apple has 5crewed. They think they can play with the s/w written by the real hackers and have no consequences. There is a basic rule in any kind of commerce around warranties. if you modify something, the device is no longer the responsibility of the manufacturer. These stupid children think that their actions dont have consequences. They get angry when they are forced to suffer the consequences of THEIR actions.
Gotta love this narrow point of view. There is something called "the rest of the world" It is where iPhone hasn't been made available to them. To MOST of the people from there, the only reason for hacking is to unlock it. They just want to get to use it, let alone being able to install 3rd party apps.
