While it is true that the PlayStation 3 cannot update if it is off, the playstation does not need to be continually on. If you know that an update is needed, you can turn it on, update the playstation, then turn it off. If the playstation is not downloading the update or applying the update it can be turned off. An update can't even be started without the user explicitly starting the update. Depending on your internet speed, updates can be fast (< 5 mins) or slow (hours).
First you need to update the system and then go onto the PlayStation Network in the xbm menu and there you should be able to see the playstation home icon just click on it and it will start downloading. pankomputerek
