I was just noticing my iPad 2 64gbWiFi has 4.3.3(8J2) on it..as far as jailbreaking is concerned when his jailbreakme DOES come out..it will work even though it says that right..I was reading on another board about 8J2 and 8J3 I had no idea what they were talking about
From what I have read, it will work for iOSs from 4.2.1 to 4.3.3.
