Jailbreak iOS 5 GM Using Sn0wbreeze 2.8b8 and redsn0w 0.9.9b3

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 useredsn0w 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 

Since Redsn0w 0.9.9b3 is a tethered jailbreak for iOS 5 GM build, there is no point in trying this latestfirmware on iDevices. Chronic Dev team is reportedly working on a new untethered jailbreak tool, so be patient. Let them release the final jailbreak.

If you’re a third party app developer, hit the following links to jailbreak your firmware

• Redsn0w 0.9.9b3a for Windows
• Redsn0w 0.9.9b3 for Mac

Besides Redsn0w, Sn0wbreeze is a tool to consider, assuming that you’re using an iPhone 4, iPhone 3GS, 3rd-generation iPod touch, 4th-generation iPod touch and the first-generation iPad. iPad 2 and iPhone 4S support is not present as of yet.

** REMEMBER TO BOOT WITH "iBooty" **

This is a tethered jailbreak: this means that you’ll need to plug your device into your computer running a special application whenever your device is powered on, in order to boot it into a jailbroken state. We’ve included steps on how to perform this at the end of this guide.
You’ll need:

1. A supported device running iOS 5.
2. The latest version of Sn0wbreeze, which you can download from here.
