Yes it is a tethered jailbreak so you cannot reboot the 3Gs on it’s own after the unlocking process and will need a computer with redsn0w installed. Old bootrom 3Gs’s can enjoy an Untethered Jailbreak. Pay careful attention as this is not the easiest thing to do. All you will need is to download Redsn0w 0.9.11b4 from below
