The iPhone DevTeam has updated redsn0w 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.
As a special bonus to Windows users, the iPhone DevTeam made it so that if you make a copy of redsn0w.exe and name it something like “justboot.exe” (anything with the word “boot” in it), it will start up in “Just Boot tethered” mode. That way you don’t have to click on any buttons at all to boot tethered!
