PS3 Firmware Update 3.42 is Now Available, Details Incoming
Update: Several users who updated to PS3 Firmware 3.42 have now confirmed (along with Sony directly) that Sony has indeed added 'additional security features' and patched the PS3 exploit used for PS JailBreak, PSGroove and PSFreedom as expected so it is advised you do NOT update if you plan to use them.
For those who just signed in to PlayStation Network, PS3 Firmware update 3.42 is now available to download.
Now I get to update one PS3 and leave the other offline forever.
edit: And I was gonna deactivate all my accounts on my other one, but they didn't give me time
edit2: DO NOT UPDATE YET!!! Use LG5Tool.exe (Logan5's Tool, theres a download link here on the forum), it works just fine, as I'm deactivating all my accounts right now, running 3.41, when current is 3.42.
