Another firmware update from Sony, just when some of us were thinking they were done with updates for the PSP while they focus on the new PS Vita. Sony now skips through the firmware rate and goes to 6.60. Its confirmed that signed eboots (homebrew and apps) still work. However downgraders report unsupported firmware. Sony has patched the 6.39 kernel exploit and we need a new exploit for 6.60 Custom Firmwares now.
