In a nutshell, PS3 Firmware 4.41 is a minor PlayStation 3 update that will improve system stability. I just got prompted to do a system update. Looks like no online until some PS3 CFW news appears, however, the encryption keys and the passphrase is still the same.
Below is what the Tweet states, to quote: "PS3 software update v4.41 is coming today, it's a minor update that will improve system stability."
As always, more details and an official changelog will be posted once they become available.
Below are some changes from eussNL as well:
Kiosk/Shop/SEX was also changed – same deal as retail of course. Still downgradeable and modifyable logically...
Its desperate for system updates. The latest Vita update his finally made it stable where it used to lock up daily.
The PS3 locks up after about 20 mins of gameplay, then when you restart its fine after that. Luckily its usually after the game auto saves or after a level and when your back in a menu. Not many times does it lock up in the middle of gameplay like the WiiU does.
It looks like this is related to the latest PSN maintenance, maybe they did something like changing the passphrase or changing the way the PS3 authenticates with PSN, so a 4.41 spoofer might not be enough for CFW PS3s to connect to PSN.
