iOS 5 iPhone-iPad-iPod Touch Tethered Jailbreak with Redsn0w 0.9.9b5

Tethered jailbreak means you’ll have to plug in your device to your computer every time it reboots to make a “Just Tethered Boot” from redsn0w. Untethered iOS 5 Jailbreak Means, you will not have to Plugin your iOS Device to Windows/Mac Computer every time you reboos to Make “Just Tethered Boot” from Redsn0w.

Thanks to the work of the iPhone Dev-Team, you can tether-jailbreak your iOS 5 device using Redsn0w 0.9.9b5 by following this simple tutorial.

From the iPhone Dev-Team Blog:

With today’s official iOS5 release, redsn0w has been updated to 0.9.9b5 to include the public URLs for the IPSW files.  This way, first-time iOS5 jailbreakers don’t need to supply the IPSW file manually.  It’s still a tethered jailbreak on all except the old-bootrom iPhone3GS, and it doesn’t apply to iPad2 or the upcoming iPhone4S.

Because the jailbreak is currently only tethered for most devices, we’re not going to release a new PwnageTool yet.  Instead, we’ve decided to build some of PwnageTool’s functionality into redsn0w (since you need redsn0w to “Just boot tethered” on every power cycle anyway).  The new “Custom IPSW” button on the Extras screen will create a custom IPSW without the baseband update for 4.3.3 or 5.0gm (iPhone3GS and iPhone4 only, for now).  Remember not to accidentally restore to the stock IPSW after you create the custom one!  The custom one begins with NO_BB_ (for “no baseband”).

You must enter “Pwned DFU” mode before trying to use the NO_BB_ IPSW with iTunes (and your hosts file cannot be pointing to Cydia’s servers due to the new blob nonce mechanism they’re using in iOS5).

Version 0.9.9b5 is available only for Mac for now, until we can do more testing on the Windows version of “Custom IPSW”.

We’re currently working on a normal compatibility update for existing ultrasn0w unlockers.  After that we’ll try to fix the iBooks issue on jailbroken iOS5.

Things to remember :

  • This will not work with iPad 2, nor the iPhone 4S
  • This is a tethered jailbreak, meaning that it will require you to connect the phone to a computer running Redsn0w whenever you power up the phone.
  • As has been the case before, by pursuing the tethered route, if and when an untethered jailbreak does surface, the chances are you’ll have to restore in order to utilize it.

Untethered iOS 5 Jailbreak with Redsn0w is possible in some Time, and Untethered Jailbreak is the Best way to JAILBREAK iOS 5 .

Important Note – iOS 5 iPad 2 Jailbreak is not Supported with Redsn0w. Jailbreak iPad 2 can be Jailbroken with Untethered iOS 5 Jailbreak iPhone 4S coming in Few Days from Now.
