These are instructions on how to jailbreak your iPhone using a custom restore ipsw and RedSn0w for Windows.

**At this time you cannot generate a custom restore ipsw using Windows. You will have to download one or get it from a Mac friend. You may find it easier to use one of the simple jailbreak options like Limera1n or Greenpois0n.

Step One
Create a folder on your desktop called Pwnage


Download RedSn0w from here and place it in the Pwnage folder. Likewise, download the latest 4.1 firmware for your device from here.

Extract the redsn0w zip that you just downloaded into the same folder.

Step Four

Thanks iClarified, iPhone Dev team, and everyone else! I just used this article, to upgrade two iPhone 3G (one on 3.1.2 and the other on 4.0.2) to 4.2.1 using a custom firmware created on a MAC and RedSn0w for Windows 0.9.6b6. Both updated successfully while retaining the 05.13.04 baseband and both have also been unlocked successfully. Thanks again!

The latest version of Redsn0w crashes for me. When I'm on the ram-disk mode, then the program crashes (on window) and says the program stopped work.

Does redsn0w affect the baseband or should I use Pwnage to update to 4.1??

Hi, I followed this tutorial, and I keep getting a "iphone could not be restored unkown error 6" everytime and every time i restart the process and after deleting Itunes library and other custom ipsw files from my comp. I'm on a Vista laptop, and right now I'm pretty much out of ideas escept for maybe doing an official Itunes restore...Anybody encounter the same error 6 along the way and if yes, do the experts have any fixes???Thanks

Hello guys, is there a possibility for me to update my 3GS which is on 3.1.3, which i got recently (blackra1ned and relies on unlock), since its not a factory unlocked phone. Since i got it recently there was no ssh saved for anything later than 4.1. Which is the far more reason i need to be more cautious in doing the upgrade a problem free one. So will this work for my situation. Looking forward for an reply and thanks a lot in advance guys....!!!! :-)

I buy a iPhone 3GS and it comes with new baseband!!!@#@# If I use this Jailbreak with Custom Restore it will downgrade the baseband? Can I unlock or need to wait?

----- WARNING ------ ALWAYS use a custom firmware IF you want an unlock. Standard Apple firmwares (ipsw) upgrade the baseband and usually make an unlock impossible. Do not use unless you know what you're doing.

Yes sure it's safe from update baseband,work very well.

I would not do it... you can update to 4.01 or 4.02 but why 4.1 ? you will probably mess it up and update your baseband. I'm not saying you cannot do it but your question shows that you're not totally into the material. So my advice is just update your 3GS so 4.0 and you'll be fine. If you need help write me an e-mail.

@Kas, i have an iPhone 3G iOS 4.1 jailbroken using Redsnow 0.9.6b1, everything works fine except that my speaker dock no longer working with my iPhone now. i've tried with other, iPhone 4 iOS 4.1 jailbroken using GP RC4 and it works on my speaker dock..... does anyone have the same issue like mine? should i re-jailbreak my device (the 3G) with 0.9.6b2 ? to make it works on my speaker dock ?
