iPhone Dev-Team released a RedSn0w update fixing an issue for old bootrom iPhone 3GS owners looking to install UltraSn0w 1.2.5. iPhone3GS owners in our comments section below noticed a problem with the untethered jailbreak available for the old-bootrom 3GS. We’ve corrected that problem in 0.9.9b9d.
If you have an old-bootrom 3GS and have already used last night’s redsn0w on it, you can re-run it again without losing anything.
