How To Jailbreak iOS 5.1 Semi Untethered With Sn0wbreeze 2.9.2 iPhone 4, 3GS, iPod Touch 4G, 3G & iPad [ Download ]

Well, iH8sn0w the well known developer and hacker has released Sn0wbreeze 2.9.2 to jailbreak iOS 5.1 on iPhone 4, iPhone 3GS, iPod touch 4G, 3G and iPad. Sn0wbreeze is a jailbreak tool which will allow you to jailbreak iOS 5.1 on Windows only. Follow our guide after the jump.

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 is new with 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.
