"On April 1, Sony released firmware update 3.21 for the PS3, an
update that disabled the Install Other OS function on the older,
bulkier PS3s. Sony's official reason: "Security Concerns."
"Now, nearly a week later, consumers are reporting that the
update has led to a variety of bugs, including slowed internet
connections, controller compatibility issues, and resolution issues
when using HDMI. And that's if the update installs at all, as there
have been reports that the download cycle hits an endless loop and
never fully completes."
