I unknowingly updated my 2 PS3's to 3.73 then found out I was screwed. I have been waiting for the past year hoping firmwares above 3.55 would be broke. I didn't want to open my PS3 and do the E3 thing. I then ran across this forum post. I sent my 2 PS3s to playerkp420 and I'm happy to say I now have my 2 PS3s back in my hands with 4.31 CFW!!! I couldn't be happier! It only took about 2 weeks from send to receive back. Send your PS3 to playerkp420 with confidence!
