Tomorrow Sony will be releasing a new system software update (v4.20) for PlayStation 3 which will include a few minor updates in order to strengthen functionality. System software update (v4.10) added a feature that enabled users to hear their own voice through the Wireless Stereo Headset when playing multiplayer modes. This type of audio feedback is known as "sidetone." System software update (v4.20) will improve sidetone audio performance by giving users the option to select one out of five levels for microphone audio, or turn the feature off completely. For those who use the Wireless Stereo Headset to watch Blu-ray or DVD movies on theri PS3, this system software update will also enable virtual surround sound functionality.

This update will also allow users to set the amount of time that the system will wait before turning itself off automatically for [Video/TV/Music/Photo] and for [Game/Other Features].

Additionally, saved data management has been improved. Users will now be able to select multiple saved data items and delete or copy them as a group.
