According to MaxConsole, the latest PSP 3000 is now hackable thanks to Datel's newest tool. Datel will launch the tool on Nov 28, 2008 and would possibly be the hottest PSP accessory of the year.
Appropriately named the Lite Blue Tool, this battery would make the Pandora battery obsolete. The Lite Blue Tool does what others would think is impossible, that is to hack into the PSP 3000 and make it go into service mode. When in service mode, you can do wonders into its firmware, in short you can downgrade your firmware into any PSP firmware you like.
It will damage your wallet for a cool USD$29.99 when released.
