Good news! Sn0wBreeze 1.6.1 has been released! iH8sn0w, the developer behind Sn0wbreeze jailbreaking tool has just released the updated version which supports jailbreaking iPhone 3G/3GS-old boot/iPod Touch 2G and iOS 4.0 on Windows. Sn0wbreeze 1.6 is nothing but the PwnageTool port to Windows and hence it can create custom firmware for iOS 4.0 while preserving baseband to keep your iPhone unlocked, unlike redsn0w.

PwnageTool 4.01 was released yesterday by the iPhone dev team to jailbreak iOS 4.0 on iPhone 3GS. But PwnageTool is only for Mac. For Windows users, RedSn0w 0.9.5 beta 5 was the only jailbreaking tool available which doesn’t work for iPhone 3GS.

If you have iPhone 3GS with old bootrom and already pwned on 3.1.2 with anything other than Spirit, then download Sn0wbreeze 1.6.1 for Windows and get it jailbroken now.

Guide to Jailbreak iOS 4.0 on iPhone 3G/3GS and iPod Touch 2G using Sn0wbreeze 1.6.1

As I already mentioned, Sn0wbreeze is just a windows port of PwnageTool 4.01. Hence only following devices are supported
iPhone 3G/3GS (old bootrom/already jailbroken with anything other than Spirit)

Here is a step-by-step guide for your reference

5. Click on “Yes” when Sn0wbreeze asks you “Do you want to activate your iPhone?” for hacktivation. Click on “No” only if you are on an officially supported carrier like AT&T.
