Unlock Iphone 3GS

[udushyant]

I am totally new to Jailbreak/unlock Iphone. If I jailbreak my 3GS(FW 4.2.1), using Greenpois0n, will I be able to unlock my Iphone?

Thanks,

hello! first of all you need to be on the right baseband to unlock the 3gs...

Before you can follow these instructions you must have a jailbroken iPhone and you must be on the 04.26.08, 05.11.07, 05.12.01, 05.13.04, 06.15.00, or 01.59 baseband(modem firmware).

Thanks for your quick response.

My Modem Firmware is 05.15.04. I will Jailbreak with Greenpois0n. Then will I be able to unlock?
