I would wait until someone well known confirms 3.56 custom firmware, and it didn't make news so I doubt its real.
Just my two cents..

If the description has "WARNING", "NO PROOF", or "I saw it on youtube" then say away from it.

I wish i could test it and give you guys proof if it does work but im banned from TTG an cant get the download link do you think any of you guys could go there and get the link and upload it to either megaupload or mediafire? I have a pvr so ill make another respond with a video if it works but I need the link first im banned from TTG so again please if could send me download link to it

i think u need a real Jailbreak 4 it like the E3 card reader or ipod or something

No point..if this was working, believe me it would be on the front page of the New York Times by now!..lol So until you see it posted here, or anywhere else as working then seriously avoid it. It's just going to be more BS that doesn't work just like all the hundreds of other "3.56 CFW" that don't work or just 3.56 OFW.

well i have notthing to do right now yah an i dont care if i brick ps3 or something like that or service idk but i want my ps3 to be bricked so yah still if could please send

It's just 3.55-JB re-named.

Thanks for the confirmation +rep for you

I want to JB badly but I updated to 3.56. I see all these ways but most are fake and Im not putting my ps3 into service mode to try it. Someone crack and confirm 3.56 please!
