Hi, I`ve been away for a long time and couldn`t have time to follow the latest jailbreak news! I have an iphone 4 on 4.1 firmware and 02.10.04 BB. What s' the latest untethered JB and does it really worth Jailbreaking again. I`m happy with my 4.1 but I wouldn`t mind few upgrades etc. Thanks for help.
