The baseband has nothing to do with the jailbreak mate , once you go up a firmware your baseband will go with it but it doesnt matter , its the fw 4.3.3 , the baseband only plays a part in the unlocking of an iphone , for example , i updated my daughters 3gs to the ipad baseband just to gain the unlock , doesnt have any bearing on the jailbreak. 4.3.3 is untethered , to test it just turn your iphone off, , and if it comes back on , on its own then thats ya proof its untethered
