Now if you have updated your firmware to 4.3.3 then of course I say jailbreak. But if you have a jailbroken iDevice on 4.3.2 or 4.2.1, etc and you have no problems with it then there is no reason to update. The new firmware came out days ago and the only main difference in 4.3.3 is that it resolves the tracking issue which doesn’t do anything but just to please people it has been fixed. Even if you do want this fix then just go to Cydia and get search for Untrackerd. Install this and the job is done. Here is the video if you do want to jailbreak untethered 4.3.3:
