Please don't forget to tell us how it goes in the comment section below and if if this guide was any help.

Update:

Based on reader comments, we wanted to clarify the following points:

* Redsn0w does not jailbreak iPhone 3GS as of now. We will let you know if Dev Team releases an updated version of Redsn0w which jailbreaks iPhone 3GS.
* Please note that this guide only jailbreaks iPhone 3G running iPhone OS 3.0, you will need to install UltraSn0w via Cydia to unlock iPhone 3G. You can checkout our step-by-step guide to unlock iPhone 3G using UltraSn0w.
* Please use Firefox to download the firmware file as IE seems to automatically extract the file (thanks carny for the tip).

This seems like a very good tutorial, but i feel anything could go wrong and I have no idea what to do if something does go wrong.
