Unban Your Console With PS_Unban

Updated 12/23/2012: Here is a piece of PlayStation 3 homebrew that many will find helpful. Developer 0x00 has released a tool that allows you to unban your console and regain access to PSN/SEN. However do note that this unbans your console and not your banned PSN/SEN account. This release offers two version, one for CFW 3.55 and another for CFW 4.21. (Although he does mention that the one for CFW 4.21 works on both) The developer also claims that using his tool, even though you are not banned, could help prevent your console from been banned. That refers to console ban, so this does not prevent a PSN/SEN account ban from what I have understood from the posts by the dev. It is required that you switch off your console prior to using this and you are required to follow the same procedure every time you want to access PSN/SEN. In the initial release many were faced with a black screen but version 0.1.2 fixes this. More below from the dev himself.

Developer 0x00 is back with an update to PS_Unban. This release fixes the blackscreen issue some are experiencing. Please note that these versions should only be used by those who are experiencing the blackscreen issue.

psx-scene member GTAV90 has also informed us of what he has done using this update on Rogero 4.30 v2.03 CFW. One aspect that jumps out at me is the mention of Trophy loss. So be warned.
