I'm on FW 11.50 (fortunately I've been busy since May and didn't update to 11.52) and am waiting for a potential exploit to be revealed after theflow0 was awarded a bounty for finding a vulnerability a few weeks ago.
I was happy using PSN and my PS4 Pro untill recently, when I wanted to try using my PSVR to do some racing sim. I was honestly appalled that some content is now unavailable from PSN, specifically the Dirt Rally DLC. Now I can't even pay to get the software! The whole situation made me feel like I didn't own my own hardware. So finally, screw Sony, I'm going to jailbreak as soon as I can.
