[silverfox0786]

The video tutorial after the break will give you step-by-step instruction on how to jailbreak iPhone 4, iPhone 3GS using Redsn0w for iOS 5.


Here are some important points to note before you proceed.

•This guide is meant for iPhone 4 and iPhone 3GS users only. But the video tutorial can also be used by iPad and iPod touch users as the process involved is quite similar (and you can get the appropriate direct download links here).
•Please go through our latest status update on jailbreaking iOS 5 to figure out if you should jailbreak iOS 5.
•Redsn0w 0.9.9b4 only supports a tethered jailbreak, which means that you need to connect your iOS device to the computer on every reboot.
•If you want to unlock your iPhone then please don't use this guide as Redsn0w doesn't preserve baseband. You should wait for Dev team to release a new version of Redsn0w, which is expected to include the PwnageTool functionality or use Snowbreeze for Windows.
•Please note that jailbreaking your iPhone may void your warranty and hence proceed with caution and at your own risk.
•Please do not forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone.
•If you've jailbroken your iPhone then you can use jailbreak apps such as AptBackup, PkgBackup or xBackup from Cydia to take a backup of all the jailbreak apps and tweaks so you can reinstall them easily after successfully jailbreaking your iPhone rather then installing them individually. However, since you're moving from iOS 4.x to iOS 5, it may be a good idea to reinstall the jailbreak apps to avoid compatibility issues.
•After the jailbreaking process is complete, do not forget to checkout our article on tips to keep your iPhone secure.
•Please ensure you are running latest version of iTunes i.e. iTunes 10.5 or later.
We want to reiterate that if you want to unlock your iPhone then you shouldn't use this guide as Redsn0w doesn't preserve baseband.
