RedSn0w Gets Updated for iOS 5 GM Seed
RedSn0w has been updated to 0.9.9b3 to auto-detect iOS5 GM firmware, reports the iPhone Dev-Team.
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 :)
You can download the new version of RedSn0w from here.
