Hello! My wife and I both have 3GS. Mine is jailbroken and unlocked with 4.3.3, 6.15.00. My wife's is not jailbroken and is on 4.2.1, 5.15.04. I have tried to update her phone to 4.3.3, but I get the 3194 error. As I read around, I seem to get conflicting solutions for this. They also seem to be geared towards people who are trying to downgrade their OS. Does the problem with my wife's phone exist because another phone (mine) is on another baseband? Because it's jailbroken? Will I have to use another CPU, or is there a fix? Thanks!
