HowTo: Jailbreak/Unlock iPhone OS 3.0 Using RedSn0w ( 2G & 3G )

RedSn0w is the tool to use if you are a windows user and you want to jailbreak iPhone OS 3.0. The process is extremely simple and you basically cant screw things up, but seems that some of you have some trouble with it. So i decided to create a tutorial on how to do it. I also did a tutorial on how to jailbreak iPhone OS 3.0 on Mac so i had to do a tutorial for windows as well.

First thing you absolutely need to do is to read iPhone Dev-Team’s notes on redsn0w:

1. GOLDEN RULE: If you are using a 3G iPhone with yellowsn0w and rely on yellowsn0w to obtain cellular service, then you should NOT use redsn0w right now. Ultrasn0w (the 3G carrier unlock) is not included with this release and therefore your baseband will be locked and unable to use an operator other than the official one it was bought for. UltraSn0w will be released via APT (cydia and icy) soon. If you have an original iPhone (1st generation) then 3.0 carrier unlock works with this redsn0w release.
2. Yellowsn0w in its current form will NOT work with the baseband version that is present in the 3.0 update, you will need Ultrasn0w, which will be released sometime soon, Ultrasn0w will work with all iPhone 3G models (but not 3GS), even ones that were previously unlockable, Ultrasn0w (when available) will be released via APT (this means you will be able to get it via Cydia or Icy).
3. Please read all parts of this post before downloading and using these tools.
4. Read items 1, 2 and 3 again and again.
5. At the bottom of this post are the bittorrent files for the latest version of redsn0w.
6. This app is suitable for the recent 3.0 release
7. redsn0w will NOT work for the iPhone 3GS.
8. redsn0w WILL work for Original iPhone (1st Generation), Original iPod touch, iPod touch 2G and the iPhone 3G (not the iPhone 3GS).
