iPhone Dev team had released Redsn0w 0.9.8b7 for the new iOS 5 beta 6 firmware file that Apple had seeded only for iPad 1, without changing the version number (in case you are wondering why Redsn0w 0.9.8b7b and not Redsn0w 0.9.8b7).
Dev team had also added support for iOS 4.3.5 and iOS 4.2.10 in Redsn0w 0.9.7. Earlier, you had to point Redsn0w to iOS 4.3.4/iOS 4.2.9 firmware files as a workaround.
Dev team has provided the following information on their blog:
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 that 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.
Redsn0w 0.9.8b7b supports the following iOS 5 devices:
iPhone 4 (GSM)
Redsn0w 0.9.8b7b supports only a tethered jailbreak, which means that you need to connect your iOS device to the computer on every reboot.
As always, let us know how it goes.
