How To: Jailbreak iOS 5.1 Firmware Tethered With Sn0wBreeze v2.9.2 On iPhone, iPod Touch, iPad [Windows]

iH8Sn0w recently updated the Windows-only Sn0wBreeze Jailbreaking tool to version 2.9.2 to Jailbreak the iOS 5.1 firmware tethered. For those of you who have never Jailbroke their iPhone, iPod Touch or iPad with Sn0wBreeze before, it is a different process than Jailbreaking with tools like RedSn0w. This is because Sn0wBreeze creates a custom IPSW (firmware file) that must be restored to your iOS device before the Jailbreak takes effect. Although this means you will lose the content that is currently on your iPhone, iPod Touch or iPad, it does open yourself up to the ability to customize every aspect of your Jailbreak and of course allow unlockers to update to the iOS 5.1 firmware without updating their baseband.

If you are looking to Jailbreak your iOS device running the iOS 5.1 firmware tethered then you will be glad to know in this how to guide from you will learn how to do just this on the Windows operating system.

Note: Sn0wBreeze does not support Jailbreaking the iPhone 4S or iPad 2 (A5 devices).
