I updated my 3GS to 4.1 before i jailbroke it with pwnage tool. The jailbreaking went well. But I can't seem to unlock my 3GS with ultrasn0w. My baseband is 05.14.02. Is there any other way to unlock it? Should I use a different jailbreak program like greenp0ison? I need my phone for work pls. help
