In mother Russia, Sony jailbreak you! And thats exactly what’s going to happen if you attempt to run any of the new jailbreak softwares that are available for the PS3.  This is caused by the fact that once your Playstation 3 has been hacked, the software ID from the unit changes and Sony can detect this. Of course, if you don’t wish to ever do anything online with your PS3, from the PSN Store to friends list and online play, then sure you can just stay offline and Sony will never know. But once online with it, Sony has the power to detect the new invalid ID and ban your PS3 from the network. According to the hack creators:

 Sony does currently ban PSN/consoles that results in the 8002A227 error code…[So], as people start getting their PSjb in the next few weeks, we highly advise that you do not log into PSN while using the backup manager, which means no playing online.” 

So while Sony will only cut you off from the online portion of the Playstation world and not brick your PS3, is it really worth it? For me, no but for you? Probably not either. No seriously, it’s not worth it.
