The latestPlayStation Portable firmware, originally meant to be released on November 11 to coincide with the Japanese launch of the PlayStation 3, was released earlier today. But just hours after version 3.00 was made available by Sony, the firmware was upgraded again, to 3.01. The "update to the update" patches a security hole which is rumoured to have left open a way of bypassing the homebrew block on the handheld. The update isn't available for download on www.yourpsp.com yet, but users with a Wi-Fi connection can go to the "network update" section on their PSPs and access the update from there.
