iPhone Dev Team

Good news is here for those anxiously awaiting an iOS 4.3.x untethered jailbreak solution. Ever since Apple stepped up the cat and mouse game by patching recent exploits, the development community has been working hard to find a new way forward. As it turns out, developer Stefan Esser (i0n1c) found a new exploit and has already put it into the hands of the iPhone Dev-Team for testing.

He recently posted a video of the untethered jailbreak in action on an iPod touch running iOS 4.3.1. All eyes are now on the Dev-Team, awaiting confirmation that the method will be incorporated into existing tools and released to the public.

iPhone Dev-Team has packaged the jailbreak solution released by Chronic Dev Team along with some extra features into Pwnage Tool 4.2. This latest incarnation of Pwnage Tool provides an untethered jailbreak on Mac OS X for all recent iOS devices running firmware 4.2.1 and the Verizon iPhone running 4.2.6.

One key advantage of using the Pwnage Tool will appeal to unlockers, as these individuals can safely restore to a custom 4.2.1 IPSW while keeping their current baseband and unlock. Two problems that were reported with the GreenPois0n jailbreak have also been fixed, including iBooks not opening as well as Wi-Fi issues on the Apple TV 2.

The long awaited untethered jailbreak for iOS 4.2.1 is here, albeit in limited fashion. The instructions below pertain to Redsn0w 0.9.7b1, a beta release of the so-called "backup plan" untethered jailbreak. This release is not the final release and, being a beta, requires a bit more effort than the eventual final release should. This jailbreak is also limited to the iPhone 4, iPad and iPod Touch 4G.

The following provides step-by-step instructions on how to jailbreak your iPhone (or other iOS device) using Redsn0w 0.9.7b1.

Dev-Team are in the final days of developing the next jailbreak solution upgrade for iPhone 4 users running iOS 4.2.1. Release could even happen this week if recent Twitter activity from team members is to be believed. Most recently MuscleNerd announced that "it’ll be here by Xmas (not because we’re sitting waiting for Xmas, but because it’s achievable deadline)" when asked about an untethered jailbreak via Twitter.

Although he has since removed the post, an earlier message from comex pointed to a release before the Christmas holiday. When asked "I want a 4.2.1 untethered jailbreak for christmas :P" by another Twitter user, comex replied, "you’ll get it."

iPhone Dev-Team has released new information on the free carrier unlock software package known as ultrasn0w. Now iPhone 3G and iPhone 3GS devices running baseband versions 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00 are unlockable after jailbreaking. iPhone Dev-Team includes detailed ultrasn0w information in their recent Ultra-recycle blog post.

Running iOS 4.2.1 on your iPhone 3G/3GS? Updating your iPhone baseband to 06.15.00 using iPad 3.2.2 firmware actually makes the device unlockable for use on carriers other than AT&T Mobility. Dev-Team has developed a PwnageTool 4.1.3 Unlock Edition that will update the 3G/3GS baseband, and the group is working on a new version of redsn0w that will add this functionality for Windows users.
