Sony has announced that firmware update 4.11 is now available for download on your PlayStation 3 via PSN (still not the SEN). The update is optional. Below is the official post from Sony:

“Later tonight we’ll be releasing an optional system software update (v4.11) for PlayStation 3. This minor firmware improves certain aspects of system software, and is not mandatory to connect to PSN.

Again, this update is optional in the US and Canada, and can be downloaded by selecting System Update from the Setting column of the XMB.”

Sony says optional however, Analog Hype is reporting “the update is only optional if you live in the US or Canada, PS3 users elsewhere are required to download firmware 4.11 if they wish to access the PlayStation Network”.  Interesting. We’ll let you know if more details on this update are are revealed.
