Hi all. So I have a ps3 that I've had since November 2009 (I guess that means it's a launch model). And I'm wondering if there's anyway to downgrade it. I heard it's possible with an iPhone... here's the tools I have: 1) Slim PS3 with firmware 3.50 2) iPhone 3g with ios 4.2 jailbroken with redsn0w (can downgrade if necessary) 3) PSP 2000 with 5.50 gen CFW (can dowgrade if necessary) 4) PSP Go with 6.20 TN-A (once again, can modify firmware if necessary) Is it possible to downgrade or do something with this? Also, is there a custom firmware for the ps3 yet?
