A couple of days ago, Redsn0w 0.9.9b9 has been released to jailbreak iOS 5.0.1 for iPhone 4 and iPhone 3GS users and of course this version is a tethered one, but today some iPhone 3GS was facing a lot of problems during jailbreaking, so that the Dev Team was quick at fixing a bug that affected iPhone 3GS owners with older bootrom. This fix comes with RedSn0w 0.9.9b9d which was released earlier today.
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. Just use this new version, go to Extras->IPSW and manually select the 5.0.1 IPSW, then go back and Jailbreak it again (but you can uncheck Cydia because it’s already installed).
