Redsn0w 0.9.8b7b Includes Untethered 4.3.5 Jailbreak for Old-Bootrom 3Gs
A few days ago the dev-team released redsn0w 0.9.8b7 too add support for 4.3.5 and 4.2.10 IPSW files and to fix an issue with the iPad1 and was supposed to fix the 4.2.10 tethered issues. However, it did not fix the 4.2.10 issues so Redsn0w 0.9.8b7a was released soon after.
Today, they released another revision Redsn0w 0.9.8b7b that adds support for iOS5 beta 7 IPSW files. This update also allows old-bootrom 3Gs owners to have an untethered 4.3.5 jailbreak as well as re-enabling custom boot logos and verbose bootingC. This is for old-bootrom 3Gs only.
