(adsbygoogle = window.adsbygoogle || []).push({}); Alright so I've come upon several tuts on other sites like ps3hax, ps3 news etc on how to play online after the bans on a new account , unbanning a banned account seems impossible but that doesn't mean you can't just update to 4.30 CFW and use a new account. So just wondering since my 3.55 got banned already should I change mac address before updating to a 4.30 CFW ? Will it matter ?

No your MAC address dosent really do anything
its more about the safety of console banning. (PSID and/or Console ID)
