The well-known iPhone hacker iH8sn0w has announced the release of Sn0wbreeze 2.9.2 to jailbreak 5.1 on iPhone 4, 3GS, iPad 1, iPod touch 4G, 3G. If you not familiar with Sn0wbreeze, it’s a jailbreak tool that allows you to install Cydia on the above mentioned devices via custom pre-jailbroken firmware. Sn0wbreeze is only available for Windows user, it also called (PwnageTool for Windows).
After killing untethered jailbreak exploit (Corona) in the newly iOS 5.1 by Apple, Sn0wbreeze 2.9.2 only brings iOS 5.1 tethered jailbreak on non-A5 devices (iPhone 4, 3GS, iPod touch 4G, 3G and iPad 1) which means that you have to connect your iDevice with your PC every time you reboot it.
What’s new in Sn0wbreeze 2.9.2:
Added Tethered Jailbreak support for 3GS/iPod Touch 3/A4 Users on iOS 5.1 (9B176)
iPhone 3GS old-bootrom users are untethered on 5.1/9B176 (as usual).
Bug Fixes (Specifically with the iPad baseband and iPhone 2G).
Re-added the iPhone Dev-Team’s iPhone 2G permanent unlock ‘BootNeuter’.
Why is There no support for A5 devices (iPhone 4S / iPad 2):
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.
