All you firmware fans have something to be excited about as Sony is releasing a new PlayStation System Software Update v4.20 for the PlayStation 3 today. The firmware update specifically addresses a new feature releases in the firmware v4.10 where users could hear their own voice through the PlayStation headset, dubbed “sidetone.” While some liked this features, others were annoyed by it while others thought their system or headset was broken. The latest update now allows for “five levels for microphone audio, or turn the feature off completely.” Another benefit for owners of the Wireless Stereo Headset is an updated audio codec for the device, allowing for virtual surround sound functionality for Blu-ray or DVD movies on your PS3.

Another minor update includes how long your PS3 will be on before the system shuts itself down for [Video/TV/Music/Photo] and for [Game/Other Features].

Updates, after the jump.

Since the recent firmware update has gone live, we’ve learned a few new details which includes the ability to copy and delete multiple save files at once. This is especially a blessing for those who save files to Sony’s PlayStation Plus cloud services. You can access this by going to Under (Games) > (Saved Data Utility (PS3™).

The new time system shutdown times include:

Video/TV/Music/Photo – After 1 Hour, After 2 Hours, After 3 Hours, After 4 Hours, After 5 Hours, Off
