I have a 3Gs with the old bootroom. I upgraded to 4.3.3 then, using pwnage tool, I jailbroke the phone. I then used Ultrasn0w 1.2.3 to unlock it. According to the dev team blog, I should have been unlocked successfully via http://blog.iphone-dev.org/post/5239805497/tic-tac-toe. Am I misunderstanding this and my phone is not really unlocked? My baseband is 5.16.02. Is there a way to confirm if my phone is unlocked or not?
