Unlock 3GS FW 4.2.1 BB 05.15.04

[soffer]

My 3Gs is running 4.2.1 firmware and has 05.15.04 baseband. I am at the end of my contract and want to unlock it. How do I unlock it? I am so new at all this but I did manage to jailbreak it using GreenPoison. Also, I am an idiot when it comes to this stuff so please use easy words. lol Thanks in advance.

G'day & Welcome to the forum!!!!

If telco's operate same here where I am in Australia (I am assuming you are not in AUS) then contact them to ask to unlock your iPhone from their network.

I will see if that is an option. Thanks for the reply!
