iPhone developer team has churned out new version of Redsn0w / Redsnow to allow you to do untethered jailbreak on the iPhone 3GS, and iPhone 4. This guide is different from the one that I wrote few days back (iPhone 4.3.3 tethered jailbreak) as this one does untethered jailbreak which means you would not have to jailbreak your device again after every reboot. Ready? Follow this guide carefully.
