This guide provides instruction on how to jailbreak and unlock the iPhone 3GS (old bootrom) firmware 4.0 using Sn0wbreeze 1.6.1 by the ih8sn0w.
If you are on firmware 3.1.3 and jailbroken with Spirit you can not go directly to jailbroken 4.0. If your iPhone 3GS has the new bootrom you can not currently jailbreak 4.0. You can figure out what bootrom you have by running f0recast, if it says Tethered Yes then you can not currently jailbreak 4.0.
You need to be on 3.1.2 firmware and jailbroken. If you need to downgrade back down to 3.1.2 make sure you have you SHSHs on file in Cydia for 3.1.2 and then follow this guide. Afterwords simply run blackra1n, edit your hosts file back to normal, and you'll be ready to follow this guide.
If you are on 3.1.3 or 4.0 and can't downgrade to 3.1.2 because you don't have your SHSHs on file you currently can't jailbreak your iPhone 3GS to 4.0.
Now that you're on 3.1.2 jailbroken we're ready to start jailbreaking to 4.0! Unfortunately this process isn't as reliable as its OS X counter parts so if you have issues you may need to restore back to 3.1.2. Hopefully new software will come out soon that is a bit more reliable, maybe someone will find some magic trick so it works properly 100% of the time . . . we haven't yet.
Lets first download everything needed.
iPhone 3GS 4.0 firmware
Sn0wbreeze 1.6.1
Launch Sn0wbreeze. Click OK.
Click the arrow.
Choose Simple Mode. Click the Arrow.
Click Browse.
Browse to the IPSW you downloaded earlier. Click Open.
Sn0wbreeze is working.
You must already be jailbroken (not Sprit) for this to work. Click I understand.
Click the arrow.
If you activate your iPhone via iTunes click no. If not click yes.
Sn0wbreeze is working.
Done! Close Sn0wbreeze.
Make sure your iPhone is off and unplugged. Launch iTunes. Hold the home button on your iPhone as you plug it in until you see the recovery screen, Hold Shift while clicking restore.
Browse to the custom IPSW Sn0wbreeze made for your iPhone (on your desktop). Select it and click Open.
iTunes goes to work.
When its done set up your phone and you're good to go! Website - Twitter
