• Redsn0w 0.9.9b5 Released - Mac Only For Now

    Just a few minutes ago, the redsn0w testers (@redsn0w_testers) Twitter account tweeted out that the iPhone Dev-Team released an update for redsn0w (bringing it to redsn0w 0.9.9b5). The primary goal behind this release was to update redsn0w with the new public URLS for IPSW files. Basically, this allows first-time iOS 5 jailbreakers to not have to supply an IPSW file to jailbreak on iOS 5.

    On the iPhone Dev-Team Blog, there was also mention that a little bit of functionality from PwnageTool was added to this release. In the Extras section in redsn0w, you can choose an option called "Custom IPSW" which will build an IPSW file without the baseband for 4.3.3 or iOS 5 GM (for iPhone 3GS and 4 only at this point). The team plans on updating PwnageTool for iOS 5 when an untethered jailbreak comes out.

    Here is the full update on what is new and important with redsn0w 0.9.9b5 (READ CAREFULLY. THE WARNINGS ARE EXTREMELY IMPORTANT):

    Update #13: 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 currently only available for Mac, until we can do more testing on the Windows version of “Custom IPSW”.

    We’re currently working on a normal compatibility update for current ultrasn0w unlockers. After that we’ll try to fix the iBooks issue on jailbroken iOS5.
    As mentioned in the title as well as the body of Update #13, this version of redsn0w is for Mac users only until more testing on Windows is done.
