redsn0w 0.9.8 beta 7b brings compatibility with iOS 5 beta 7 and ultrasn0w on iOS 4

     A few days ago, the Dev Team released redsn0w 0.9.8 beta 7, which brought compatibility with iOS 5 beta 6 for the iPad, but fortunately it was also compatible with iOS 5 beta 7, which was to be released a day later. Unfortunately, to jailbreak iOS 5 beta 7 with redsn0w 0.9.8 beta 7, an ipsw for iOS 5 beta 6 was needed, so the Dev Team released today redsn0w 0.9.8 beta 7b brings compatibility with iOS 5 beta 7 and not no more. The Dev Team managed to solve incompatibility issues between ultrasn0w and iOS 4.3.4/4.3.5, so you will be able to use ultrasn0w to unlock those versions and if you have an iPhone 3GS with an old bootrom, you will also have an untethered jailbreak. In redsn0w you must select NO when you are asked if your 3GS is new.

Update #7b: About 12 hours after we released redsn0w 0.9.8b7 with some improvements for iOS5b6, Apple went and released iOS5b7 (what are the odds of that?!?). Even though redsn0w could still jailbreak iOS5b7, you needed to point it at the iOS5b6 IPSW to do so. Today's redsn0w 0.9.8b7b lets you point redsn0w directly at the iOS5b7 IPSW instead.

We've also added some overall improvements for old-bootrom 3GS owners (where the 24kpwn exploit applies): on those devices, you can tell redsn0w to untether 4.3.5 and lower, or iOS5b7. Old-bootrom 3GS owners can once again choose custom logos, and/or verbose booting (for the really nerdy iPhone3GS fans out there!). And it allows 4.3.4 or 4.3.5 users to use ultrasn0w again.
