I own more than one PS3, and as long as downgrading is impossible, I'd like to keep the firmwares as low as possible (still got Other OS on one old PS3). I recently bought a new Slim which came with 3.40 preinstalled.
Has anyone tested Jailbreak on 3.40? Can it be modified to work (or are there any chances it will be)? Has anyone actually tested it on 3.40?
