Sony released a new v2.81 patch for its handheld PlayStation Portable. The patch addresses security and memory card issues and does not require v2.80 firmware. The patch is available in Europe, Japan, and the US.
A demo of World Tour Soccer 06 has been made available for download.
EDIT: There are currently no Memory Stick PRO Duo memory cards larger than 4GB on the market, so the fix is merely a preventative measure and doesn't affect any users at this time.
