Earlier today we told you that you could Jailbreak the iOS 5 GM firmware by pointing RedSn0w 0.9.9b2 to the iOS 5 beta 7 firmware. We also told you that MuscleNerd promised to update RedSn0w to provide auto iOS 5 GM detection (so you do not need to select the iOS 5 beta 7 firmware).
Just a few minutes ago this is exactly what MuscleNerd has done. MuscleNerd has just released RedSn0w 0.9.9b3 to jailbreak the iOS 5 GM firmware. While Sn0wBreeze v2.8b8 was just updated to support jailbreaking the iOS 5 GM firmware, RedSn0w is a cross compatible jailbreaking tool that supports both Mac OS X and Windows operating systems.
Note: This is a tethered jailbreak, meaning that each time you want to reboot you will have to plug your iDevice into your computer and re-run RedSn0w.
You can read the official word from the Dev-Team below:
Update #11: 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.
If you would like to download RedSn0w 0.9.9b3 for Mac OS X or Windows you can go to the iJailbreak Downloads Section. Additionally you can use of the download links below:
