With the recent firmware upgrade(3.00), you can control your PS3 with a PSP as demostrated in the video.
Sony has released version 3.0 firmware for the Sony PSP in Japan. The 3.0 update is now available via the Network Update feature on the PSP. Using its WiFi capabilities, the new firmware lets you access images and music on a PS3, and let you use the PSP as a remote play device for the PS3. This new firmware is able to accommodate a forthcoming add-on camera, and lets you toggle a function that causes a game to automatically load when you insert a UMD.
He is probably the America’s stupidest PS3 reseller. A man in California was mugged by the 2 men who had agreed to buy his 2 PlayStation 3 systems over Craigslist.com. The victim, a man in his 20s whose name was not released, was assaulted with pepper spray and robbed of the coveted consoles. He met the two men around 1 a.m. at a McDonald’s restaurant on Moody Street and Orangethorpe. And then, the one of the buyers sprayed the victim with pepper spray, and took off with the consoles. The suspects are described as men in their 20s. The victim said that he had advertised the consoles on Craigslist.com, and was trying to sell both items for US$5,000. PS3s retail for US$500 or US$600 per unit. Watch the video here for more details.
