(adsbygoogle = window.adsbygoogle || []).push({}); I keep seeing videos' on this kind of stuff and I am wondering if they are legit; if not, will they like brick your ps3 or something? Sorry for the nub question, I am semi-new at hacking!

Don't trust those.

Why :O? Not to doubt you but just wondering.

There isn't any 3.61 cfw. These videos on youtube are most likely keyloggers,viruses, and rats.
