The PlayStation Portable has received its most recent firmware update, version 3.72, which is now available to download.
This update has added support for more PlayStation Network titles, but the biggest feature that has been added is the ability to remotely start your PlayStation 3.
To start your PS3 using a PSP, the console must have firmware version 2.00, which is not yet been released, but considering this feature has just been added to the handheld, it shouldn’t be long.
Firmware 2.00 for the PS3 is somewhat of a mystery at this point, with this remote start being the only confirmed feature.
Be sure to check back for more updates!
