These are instructions on how to upgrade your iPhone 4 or iPhone 3GS firmware without updating the baseband.

Step One
Create a folder on your desktop called Pwnage

Download the latest version of RedSn0w from here and place it in the Pwnage folder. Likewise, download the firmware you would like to upgrade to from here and place it in the Pwnage folder.

Extract the RedSn0w zip file by double clicking it.

Step Two
Right click or control click the RedSn0w application that you extracted in Step One and click Open from the popup menu that appears.

Step Three
Click Extras from the RedSn0w menu.

Step Four
Click Even More from the Extras menu.

Step Five
Click the Restore button from the Even More menu.

Step Six
Click the IPSW button.

Choose the firmware you would like to update to from the dialog box that appears and click the Open button.

Step Seven
You will be asked if you would like to Prevent baseband update. Click the Yes button.

Step Eight
You will be told that Pwned DFU mode is required. Click the OK button.

Step Nine
Connect your iPhone to the computer, turn it off, and click Next

Step Ten
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 Eleven
Your device will be detected once in DFU mode and exploited with Limera1n.

Redsn0w will then prepare a restore image.

Step Twelve
Redsn0w will now restore the device to the new firmware.

Step Thirteen
RedSn0w will tell you when the restore has been completed successfully.

Great news guys! If you iPhone is locked by AT&T and you bought it 2 years ago it can be Factory Unlocked now! Just contact AT&T from the following link: I did it and it is free and fast! Forget about Ultrasnow/Gevey and preserving your baseband, this is the real jailbreak, haha! iclarified should post this info in every post!

iPhone 3GS on 3.1.3 baseband 5.12.10 tried this & it asks for shsh. My cydia crashed months ago so I deleted it and don't know how to reinstall it to see my shsh or get them or whatever I'm supposed to do. Ive been in safe mode for 2 months but everything seems to work. I just want to go to 4.3.2 or 5.0 because most apps require it. Any help would be enormously appreciated.

I am trying to upgrade to 6.1.3 from an iPhone 4 on 5.0.1 with BB 01.59.00 and got Unexpected Error 2831. I tried fixing it holding Home Button through all the process, I didn't get the error but Redsnow never finished and I got stucked on Recovery Mode (itunes logo). Any ideas how to fix it?

I also got "Couldn't restore" "Unexpected error (2831)" and my phone came back on just the way it was before I began. I'll keep scoping this out to see if there's a fix. I will also try using firmware 6.0 instead of 6.1.3 and see how that goes. I'm running iPhone 3GS 4.2.1 Modem Firmware 5.13.04. Thanx
