It would seem as if the PSP Slim's 1seg TV tuner has been hacked to work on the original PSP Phat. In order to make it all work, you have to get some files from a dump of the firmware update and include the flash0 memory as well as hex editing the vshmain.prx to hack the network update icon on the XMB in order to kick start the 1seg tuner.
