The guy who you see on the picture is name Charlie Miller ! He attended to a conference called Syscan, which was generally about security of systems. In there he prooved how to hack iPhone by sending a single and simple sms !

He prepares an sms and sends to the victim iPhone, after the victim recieves the sms, he could reach to the locked system files of the Operating System.

He didnt show the content of the sms to the public because of the ethical rules. But after the conference, the people from Apple came to him and asked how did he done that. He gently explained. And now the Apple company started to code a patch for this security hole. We hope that security hole will be closed on the version of 3.1 !
