PSP World Writes:
"Unauthorized hacking of the PSP has been a serious problem for Sony ever since enterprising hackers managed to run unsigned code on the PSP-1000 back in 2005. The ability to revert to an unprotected version of the firmware, and later the ability to install completely custom pirate firmware has enabled some owners to play pirated PSP games downloaded from the internet.
Clearly, defeating piracy is one of the biggest concerns facing designers at Sony. It appears that the company may be planning to take some drastic steps to deter homebrew on the device with the release of the new PSP-3000 model, but like always, the company remains very secretive about its plans."
