After releasing Sn0wbreeze 1.7 iH8Sn0w just launched a tutorial on how to jailbreak iPhone 3GS iOS 4 with Sn0wbreeze 1.7 today. As we know the newest tool works for both old and news bootrom of iPhone 3GS and iPod Touch 3G on iOS 4 firmware

And iHSn0w has elaborated the step-by-step tutorial (in its forum) specifically for all iPhone 3Gs users with New Bootrom to be able to jailbreak while at the same time running iOS 4 together on their devices. Firstly make sure your iPhone 3GS has OS 3.1.2, because it’s the requirement in order to follow the guide written in iHSn0w forum

A thing to consider that the tutorial is for an advanced user, there is a big chance of failure, if you are not too familiar with your iPhone

Make sure you have these:

• iPhone 3GS — new bootrom (check your bootrom version for Mac or for Mac)
  3.1.2 already installed or 3.1.2 installed via SHSH blobs. <– Broken blackra1n’d devices will work. (Especially if Spirit messed you up!).
• Payload Pwner-r3 for the 3GS.
• Download Sn0wbreeze V1.7 for Windows from this link
• iBooty V1.3
• LibUSB (64-Bit users read carefully!!!)
• 3.1.2/4.0 3GS firmware downloaded.

Once you have completed the above requirements then visit iH8Sn0w forum to start following the tutorial written there

Yesterday I posted a good news for Windows users about How To Jailbreak iPhone Or iPod Using BlackRa1n For Windows & now how to jailbreak iPhone 3GS Using PwnageTool but for MAC OS from Iclarified.com, there are 12 steps that need to follow and they are easy ones.
