Instructions on how to perform an untethered jailbreak of your iPhone 3GS on iOS 5.0.1 using RedSn0w for Windows. The Mac tutorial version of this tutorial is here.

This procedure will cause you to upgrade your baseband potentially ruining your chances for an unlock. Please follow a tutorial on how to update to iOS 5.0.1 using a custom ipsw if you need an unlock.

If you want to jailbreak a lower firmware version you can find the appropriate tutorial here.

Step One
Create a folder on your desktop called Pwnage

Download the latest RedSn0w from here and place it in the Pwnage folder. Likewise, download the 5.0.1 firmware from here and place it in the Pwnage folder.

Extract the RedSn0w zip file by double clicking it.

Step Two: (Skip this step if you're on iOS 5.0.1 already)
Connect your iPhone to the computer and launch iTunes.

Select your iPhone from the list of devices on the left. Now hold down Shift and click the Restore button. Restore is preferred as it won't create any wasted space on your iPhone.

Navigate to the Pwnage folder on your desktop and select the 5.0.1 firmware ipsw. Click the Choose button to continue.

iTunes will now update your iPhone to the new firmware.

Step Three
Launch the redsn0w application from the redsn0w folder we extracted earlier.

**Windows 7 users may want to try running the redsn0w executable mode as an administrator in Windows Vista compatibility. You can do this by right clicking the executable and selecting Properties from the contextual menu.

Step Four
Once RedSn0w opens click the Extras button

Choose Select IPSW from the Extras menu.

Select the iOS 5.0.1 firmware ipsw from Pwnage folder on your desktop and click Open.

When asked tell RedSn0w whether you have a new model or older model of the iPhone 3GS then click the the Back button.

Press the Jailbreak button to continue.

Step Five
Plug your iPhone into the computer and make sure its OFF then click the Next button

Step Six
RedSn0w will now guide you through the steps to get into DFU mode. You can find more help with DFU mode here

Hold down both the Home button and the Power button for 10 seconds.

Release the Power button and continue holding the Home button until RedSn0w detects the device.

Step Seven
Your iPhone will now reboot

Step Eight
RedSn0w will prepare the jailbreak data.

Step Nine
Select Cydia from the list of options and click Next.

Step Ten
Your iPhone will now be rebooted again and RedSn0w will begin uploading the new RAM Disk and Kernel.

Step Eleven
Once this is complete you will be notified that RedSn0w is done. When your iPhone finishes rebooting (5 minutes or so) it will be jailbroken with Cydia on the SpringBoard.

*As usual a big thanks to the iPhone Dev-Team, Chronic Dev-Team, pod2g, and Geohot for their hard work and contribution to the iPhone community.

try this one: I have unlocked my phone on very fast (about 6 hours total) and cheap, now i can update to any version without having to worry that my phone will be locked ever again . Only 9.99$ for phone unlocks!

I followed the following steps, my iphone ran many scripts and rebooted for couple of times.. Then it went to recovery mode and it didnt come out of that..I googled for coming out of recovery mode. For this i need to connect my iphone to my laptop. But after the jailbreak program ran, the laptop stopped recognizing the iphone (I tried all the usb ports)..When I went and checked the Device manager, all the drivers are in yellow color (Warning symbol). I am not able to connect any device to my laptop. Please help!!!

All I can give is a BIG THUMBS UP to all of you at iClarified. The tutorial is clear and easy to follow. Thank you to the Development Team for making my life awesome. I am not sure how, but it just worked. So, I post my story in detail, and maybe someone can benefit from it. My wife traded in my dead 3GS (error 28) to Apple store with $149 for a NEW iPhone 3GS, 32G, QR203xxxxxx (January 2012, cleaned up from 'qr2030ga3ns' - refurbished?), ISO 5.0.1, baseband 05.16.05, bootloader 6.4_M3S2, Model MB718LL. She was told it is a brand new, locked 3GS iphone and can not use with another carrier, except AT&T. So, I run f0rcecast and it said it is not jailbreakable and need to upgrade to iPadBB to unlock. After searching, I found out the iphone 3GS after week 28, 2011 will not work with iPadBB, and BB 05.16.05 can not be unlocked by ultrasn0w. I was so disappointed, but thinking maybe I can just jailbreak it and use it as a Touch by following this tutorial. (Although there is another site claim to downgrade it to 4.1 unlock it - in Chinese, I think it is too much work, plus lots of risk.) I run redsn0w 0.9.10b6 just like this tutorial describes (check install Cydia & unlock), and it was jailbreak. Shut it down several times and it boot without a problem. Very very happy. So, I put my T-mobile pay-to-go SIM card and it works, without running untrasn0w or anything. Wow!!! not sure what has happened. But, it work. Thank you, Thank you. The only thing I have not done is to register my iphone with Apple. I also did not try it with my sim card before JB it, since I assumed it is locked. So, maybe this iphone is a factory unlocked phone? Maybe the new Toshiba chip can be unlocked with 05.16.05 BB on the old bootloader? I also use iFaith to grab my iphone's shsh blob, thinking it will come in handy in the future, will this help? Anyway, Thank you all again for the amazing work!!!

If my memory serves me correctly, because you hadn't inserted a sim prior to JBing your device it was locked to any network. I believe that your phone is now locked to T-Mobile as it was the first sim you used.

Now after using the iphone 3GS for 1 week or so, it shows NO SERVICE. Not sure if it is 3G related problem (saw "E"-"EDGE" all the time) and I am not on a prepay minute (no data) plan. However, I did use that iphone for about a week. Try everything (you name it - reset network, airplane mode, sim in/out...), but no luck, I guess the baseband is unlockable (05.16.05) and I just got lucky to use it for a week. :(
