170w ago - 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.
While we can speculate on whether Sony blocked PS JailBreak with it, etc feel free to grab it below and report in the comments any changes you notice and we will update the news accordingly.

imo fw is partly loaded to internal, so u cant thats easy just downgrade fw, but if the system update fails mid update and just starts over and over u can get back to the one u were updating from, anyhow heard some ppl claiming to be able to go down fw by formatting harddrive but i guess thats some older machines cuz now it isnt really possible no? correct me if im wrong if it was that easy there wouldent be ppl not updating even from 1.60 xD
