Redsn0w

iPhone Dev team has just released Redsn0w 0.9.15b3 that makes it a lot easier to jailbreak iPhone 4 and iPhone 3GS, as you don’t need to go through the hassle of installing Cydia manually.

In this article, we show you how to jailbreak your iPhone 4 or iPhone 3GS running on iOS 6 using Redsn0w.

Here are some important points to note before you proceed.

  • This guide is meant for iPhone 4 and iPhone 3GS users. iPod touch users can check out our step-by-step guide to jailbreak iPod touch using Redsn0w here.
  • Warning: If you depend on Ultrasn0w to unlock your iPhone, then DO NOT update to iOS 6.
  • Redsn0w 0.9.15b3 only supports a tethered jailbreak, which means that you need to connect your iPhone to the computer on every reboot (except iPhone 3GS with older bootrom). It is currently not possible to jailbreak iPhone 5 and iPhone 4S.
  • Please note that jailbreaking your iPhone may void your warranty and hence proceed with caution and at your own risk.
