If you’re a lucky owner of an iPhone 3Gs (old-bootrom) you can now have access to an untethered jailbreak for iOS 5! Trust me the upgrade is worth it.
To upgrade to iOS 5 you are going to need:
- iOS 5
- iTunes 10.5
- Redsn0w 0.9.9b6
Now plug-in your iPhone, open up Redsn0w. Click on the “Extras” tab then click on “Preserve Baseband with custom IPSW”. Follow the instructions then go back to menu and click on “Jailbreak”. Point Redsn0w to the NO-BB… IPSW and follow the on-screen instructions. After reboot you should now have an iPhone 3Gs jailbroken on iOS 5!
