The rumour yesterday was spot on. Firmware v4.20 is now available to download for the PS3, brining with it a number of changes and fixes. Firstly, the power-save mode has been revised to comply with SCEE regulations, which means that the system will now, as default, be set to automatically turn off after 1 hour of no use.
The setting is configurable, however, from the [Settings] menu. The firmware update also improves “sidetone” when using the Wireless Stereo Headset, which was introduced in Firmware 4.10. This feature can now be disabled completely or you can choose one of five volume levels.
In addition, for those of you who use the “Wireless Stereo Headset” to watch Blu-ray or DVD movies on your PS3 system, this system software update will also enable virtual surround sound functionality giving you a superior audio experience.
Finally, the Saved Data utility has been improved, allowing you to select multiple save data items and copy or delete them as a group. This should make backing up saved data much easier.
