Sn0wbreeze 2.9.2 - Untethered iOS 5.1 Jailbreak for iPhone 3GS (Old Bootrom)

Windows-only tool adds the iPhone Dev-Team's permanent unlock 'BootNeuter'

iOS hacker iH8sn0w (real name Steven), has released a new version of Sn0wbreeze, his Windows-only jailbreak utility. The tool provides an untethered iOS 5.1 jailbreak for some of the early iPhone 3GS handsets.

Sn0wbreeze 2.9.2 adds tethered jailbreak support for iPhone 3GS and iPod Touch third-generation, as well as all A4 devices (iPhone 4 and iPad 1) on iOS 5.1 Build 9B176.

iPhone 3GS handsets with an old-bootrom can be jailbroken “untethered” on 5.1/9B176, according to Steven.

His new release also fixes a few bugs, “specifically with the iPad baseband and iPhone 2G,” he notes.

Also, he has re-added the iPhone Dev-Team's iPhone 2G permanent unlock 'BootNeuter', according to the change log.

For those asking why Sn0wbreeze v2.9.2 doesn’t support A5 devices, iH8sn0w explains that “A low level (DFU/iBoot/LLB) exploit is required to start the restoration of custom IPSWs. The past two jailbreaks (JailbreakMe & absinthe) for the A5 worked within iOS itself.”

“These exploits are not capable of bringing the iDevice into a state where it will accept custom IPSWs. Therefore, an A5 device cannot currently downgrade to an iOS revision that Apple is no longer signing (even with SHSH blobs) and it cannot preserve the baseband when updating to a newer iOS revision,” he elaborates.

“While the future may always seem to get more narrower... Keep your head high and continue to be open minded,” says iH8sn0w.

As some of you may recall, the iPhone Dev Team also confirmed support for iOS 5.1 in their Redsn0w application for Mac and Windows. Seemingly using the same exploit, Redsn0w also provides an untethered jailbreak for old-bootrom iPhone 3GS handsets.
