(adsbygoogle = window.adsbygoogle || []).push({}); I had a look around and can't find any post on hiding your ip on the ps3.
I'm about to jb my console and start hosting some challenge lobbies but don't really want the chance of getting banned.

Does anyone know any software to do this. I've looked at the proxy's but they are just for web viewing.

If they ban your console, you may be able to convince Sony that you bought the PS3 used from a game store or classified ad and you are a new owner. I doubt they would keep that console perm. banned forever. Sony wants to make money and for them to perm. ban a bunch of PS3s they potentially loose out on money from PSN downloads and such.

You forget though, SONY doesn't receive money from used consoles. (Aside from PS Store that is if the console isn't banned) I think they would much rather have you buy a brand new console.
