PSP Firmware 2.6
Sony USA has an update for the firmware for your PSP to 2.6. Not a major update. The two major updates are WMA support and RSS support. This update isn't for the hardcore PSP users since this will definitely block the homebrew apps, and emulation software. But there will definitely be someone who'll come up with a hack to be able to downgrade to previous versions of firmware if you updated to the latest firmware. Link is up @ the Sony website & at Engadget.
