The iPhone Dev-Team has released an updated version of Redsn0w that already supports iOS 5 GM. It's only been a day since Apple released the new iOS 5 and it's already jailbroken. That's great news for the JB community.
Redsn0w will not unlock your phone however, so if you need an unlock this won't work for you.
redsn0w has been updated to 0.9.9b3 to auto-detect iOS5 GM firmware. Remember: it’s still tethered for all devices except for iPhone 3GS with old bootrom. If you don’t use redsn0w to “Just boot” at power up, all jailbreak apps (and even some native ones like MobileSafari) will fail to launch.
If you already jailbroke the GM by pointing an older redsn0w at the beta7 IPSW, there’s no need to re-run the full jailbreak step again…just use this newer one to make the tethered boot easier.
