You can only update the PS3 manually either by initiating it from the System Update menu in the XMB (via internet or from an insertable storage media), or responding to an update message when you login to your PSN account. Either way, the update shows its progress on your screen as it happens, and turning your PS3 off in the middle of an update can cause a lot of problems (loss of data type problems).
PS3 is on Update 4.21 released on July 6, 2012. Update 4.11 was February 16, 2012. System Update 3.10 was November 19, 2009
Well first you have to update your system
By asking the administrator.
No, but there are system updates which apparently crash your PS3. SO I would recommend you stick to the original Sony Updates and wait for some reviews of the update before updating because some people claim that their PS3's were bricked by the 3.21 system update.
You might need to update your PS3 if that is what you have. To update offline put in your game and a message will say you need to update to version. To play online go to settings and select "update system" to update it.
