Just hours after the official release of iOS 5, the iPhone Dev team rolled out an update of its popular jailbreak tool, redsn0w, and added iOS 5 support.
You can now use the redsn0w 0.9.9b5 to jailbreak iOS 5. However, keep in mind that the tool only supports tethered jailbreaks, unless you're using the old bootrom iPhone 3GS. That means that for all mobile devices, including the iPhone 4 and the iPad 1, you need to re-jailbreak your device every time it is rebooted or runs out of battery life.
As mentioned in the team's blog, the latest version of redsn0w doesn't support jailbreaking on the iPad 2 and iPhone 4S. You'll need to wait a little bit longer before there is a viable solution.
What's New about Redsn0w 0.9.9b5
The redsn0w 0.9.9b5 has included the public URLs for the IPSW files. So, first-time iOS 5 jailbreakers don't need to supply the IPSW file manually.
On top of that, the team has built some functionalities, which were originally available only on the PwnageTool, into redsn0w. The new Custom IPSW button, which you can find on the Extras screen, allows you to create a custom IPSW without the baseband update for 4.3.3 or 5.0. Presently, the custom IPSW feature supports both the iPhone3GS and iPhone4 only.
Where to Download Redsn0w
The redsn0w 0.9.9b5 is now available for Apple computers. You can download the tool via the following link:
The Windows version should be available soon. Later, we will publish a step-by-step guide to walk you through the iOS 5 jailbreak process. If you can't wait for it, you can refer to our earlier guide, which shows you how to jailbreak iOS 5 GM. The procedures should be very similar.
