Hello guys, I am using a non-jailbroken iPhone 3GS running on iOS 4.3.3. Now, what I want to do is jailbreak and unlock it. I know that I need to update its baseband to iPad 6.15.00 in order to unlock it. I am also aware about the new Redsn0w 0.9.9b1. So, my question is; can I use Rdsn0w 0.9.9b1 to upgrade iPhone 3GS baseband from 05.6.01 to 06.15.00? If yes, then how? Thanks in advance.

Once completely jailbroken with iPad’s 06.15.00 baseband installed, you can now unlock your iPhone from its official mobile phone carrier using the latest version of Ultrasn0w. You can follow this tutorial on how to unlock iPhone 3GS on iOS 4.3.3 firmware using Ultrasn0w 1.2.3. Also, I would recommend you to backup the SHSH blobs of your device using iFaith SHSH Blobs Dumper. The tutorial on how to use iFaith can be found here.
