Am I too late to be able to update to 4.3.3. I have been updating my iPhone 4 for a while now and jail breaking it and it has always been quite straight forward but now it doesn't want to work. i have tried everything I have found so far on the net regarding adding and removing parts from the hosts file but I still get device not eligible. So far it looking like I have to stay on 4.2.1 or go to 4.3.4 but I really want to keep a untethered JB. Can anyone confirm.
