Jailbreak iPod Touch On iOS 4.2.1 Redsn0w

Few hours after iOS 5 was released, Dev team had released Redsn0w 0.9.9b4 for iPhone, iPad and iPod touch running iOS 5.

As promised, iPhone Dev team has just released a new version of Redsn0w – Redsn0w 0.9.9b5 with PwnageTool functionality. They have also added the public URLs of the iOS 5 firmware files, which means you don’t need to point an IPSW file to it any longer.

Dev team has provided the following information on their 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 to NOT accidentally restore to the stock IPSW after you create the custom one!  The custom one begins with NO_BB_ (for “no baseband”).  On Mac iTunes, you select an IPSW by holding down the Option key while clicking “Restore”.

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”.

Redsn0w 0.9.9b5 supports the following iOS 5 devices:

Redsn0w 0.9.9b5 supports only a tethered jailbreak, except for iPhone 3GS with old bootrom which is untetherd. With a tethered jailbreak you need to connect your iOS device to the computer on every reboot. It still doesn’t support iPad 2, so it is unlikely to support Apple’s new iPhone 4S.

You can download Redsn0w 0.9.9b5 for Mac using this link. You can checkout step-by-step guide on how to jailbreak iPhone 4, iPhone 3GS running iOS 5 using Redsn0w if you need help (it currently doesn’t not include the steps to create custom IPSW but we will update it shortly).
