What is RedSn0w?

RedSn0w is a jailbreak tool developed by the Dev-Team. Originally called QuickPWN, this jailbreak tool was quickly renamed, and has now become a household name for most jailbreakers. Unlike PwnageTool, RedSn0w works for both Mac and Windows, and is considered to be one of the most reliable jailbreaks by the whole community.

When Not to Use RedSn0w

Because RedSn0w used to require you to update your device to a newer version of iOS in order to jailbreak it, we used to strongly suggest that those of you who unlock the iPhone stay away from RedSn0w, as it might cause you to lose your ability to unlock.

That’s no longer the case. If you rely on an unlock for your iPhone and still want to run and jailbreak the latest iOS version available, you can use RedSn0w, PwnageTool or Sn0wBreeze. All three tools will allow you to update to a newer firmware and jailbreak it while preserving your baseband, which is the key to your unlock.
