Firmware 3.21 Additional Details Revealed

The controversial update for the PlayStation 3 firmware went live this week. A small yet vocal minority was steadfast against the removal of the Other OS option. Sony wanted to remove the feature to reduce support costs and help thwart any hackers attempting to bypass DRM and security. It appears that is not the only reason for this update as the PlayStation website reveals.

In addition to the known information about the removal of a secondary operating system as an option, PlayStation site mentions two other features.


  • The [Install Other OS] and [Default System] features have been deleted.  > See Details


  • The playback quality of some PlayStation® format software that is downloaded (as a purchase or for free) from PlayStation®Store has been improved.
  • A security patch was added to address security vulnerabilities that may occur when playing MP4 format video files.
