iOS 4.2.1 Jailbreak with redsn0w 0.9.6b4 Download Available

Update 1: Download links updated with mirrors and misc. notes.

Yesterday the iPhone Dev Team sent an update about “Thanksgiving with Apple”. Well, in less than 24 hours they have released a jailbreak for iOS 4.2.1 for OS X and Windows. From what the iPhone Dev Team wrote on their blog, the following will apply:

• iPhone3G, older iPhone3GS, and non-MC iPod touch 2G: untethered jailbreak
• More recent devices (iPhone 4, iPad, iPod touch 4G): tethered jailbreak (meaning if your device reboots, you’ll have to re-jailbreak)

Here’s the update released on their blog:

Update #1: redsn0w version 0.9.6b4 is now available for your 4.2.1 jailbreaking pleasure.  Please read all the above to understand what this jailbreak currently entails.

• PLEASE UPGRADE TO iTunes 10.1 FOR BEST RESULTS
• WINDOWS 7 USERS SHOULD RUN redsn0w IN “XP COMPATIBILITY” MODE

Currently their servers are being hammered so downloads are really slow. Your best bet is to wait and see how this latest tool works before attempting it on your own. Well done to the entire iPhone Dev Team! Their hard work is truly amazing.
