As we know Apple has killed and stopped the Untethered Jailbreak exploit "Corona" in its new iOS version iOS 5.1 so now Sn0wbreeze 2.9.2 only brings iOS 5.1 tethered jailbreak on non-A5 devices (iPhone 4, iPad, iPod 4G, iPhone 3GS & iPod 3G) 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 No Support for A5 chipset 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.
Now let’s start the Tutorial and Guidelines to Jailbreak iOS 5.1 with Sn0wbreeze Untethered method to Unlock iPhone 4, iPad, iPod 4G, iPhone 3GS & iPod 3G.
