51w ago - Following up on my guide, the way I see it Sony will soon patch my console unban method, in my opinion it will be possible to work around the patch, I however won't release it publicly but below I give you PS_Unban v0.1 for 3.55 and v0.1.2 for 4.21 Firmware.
PS Unban is a tool to unban your PS3 on both 4.21 and 3.55 firmwares (different pkg's) (the 4.21 should work on both but meh), no console ID needed.
If it gets fixed i'll patch it a few times.
Install either "PS_Unban v0.1(4.21).pkg" (UP0001-NOBAN0000_00-0000000000000000.pkg) OR "PS_Unban v0.1(3.55).pkg" on your PS3.
Update: PS_Unban v0.1.2 is now released HERE and is out of BETA so grab that version instead.

Thanks for the positive feedback, and I believe banned accounts can be 'allowed to access PSN' by manipulation of PSID i can't be sure though, maybe i'll look into it at some point, I however don't think there is a way to 'unban' them no.
I have now promoted the news to our main page and +Rep for sharing 0x00. I know after posting your guide some people were concerned you may not share it, but it's great to see you decided to do so indeed!
This reminds me of the Rebug 4.11 Version Spoofer release that the Rebug Team admitted Sony would patch when it went public, but still decided to release it anyway to 'temporarily' restore PSN access to PS3 CFW users.
It's that kind of spirit that keeps the PlayStation 3 scene alive, versus using the lameass excuse "I'm keeping it private because Sony will patch it wah wah I'm l33t" hehe if that was the case there would have been no R:FOM or Warhawk exploits, PS Vita game exploits, TN eCFW, etc.
Rock on, now the ball is in Sony's court once again...
