PSPgo Hacked, Says Hello World

While Sony went to great lengths towards preventing a repeat of the Pandora battery hack on PSPgo, they evidently forgot to patch up some existing security vulnerabilities on the software side. Mere days after the launch of the new hardware, homebrew developer FreePlay has managed to run unsigned code on it. Above is a video clip showing off his efforts in the form of a hello world proof of concept.
Taking advantage of modified save data files, the exploit is restricted to user mode, meaning modifying existing files on flash is out of the question. That means no custom firmware, kids. Still impressive nonetheless and perhaps a bit embarrassing for Sony’s engineering crew, considering how quick this feat was pulled off. Now, here’s the kicker: FreePlay has no plans to share this one with the public, but at least you can rest easy knowing that homebrew code can be run on the go.

Uhh... he's not running custom firmware. If he was, he would never have gotten the "Pause Game/Quit Game" screen when pressing the PS button.
This doesn't prove that the PSP Go was hacked. It only proves that the PSP Go had a custom "game" created for it to say "Hello World" and to show the code.
