iOS 5 Untethered Jailbreak: MuscleNerd Congratulates Pod2g for Untethering 5.0.1 (non-A5 Devices)

iPhone Dev-team member MuscleNerd congratulated rival Chronic Dev team member pod2g for being the first to release an untethered jailbreak for iOS 5.0.1 (non-A5 devices).

Both MuscleNerd and pod2g were working round the clock to find the untethered jailbreak for iOS 5.0.1.

MuscleNerd, became a big name among jailbreakers, when he found a semi-tethered jailbreak - redSn0w - for iOS 5 within a day of its release. However, redsn0w could only jailbreak iOS 5-powered Apple devices that did not run on A5 processor i.e., it could not jailbreak the iPhone 4S and iPad 2.

Last week, MuscleNerd released the redsn0w 0.9.9b9, a semi-tethered jailbreak. But it is an untethered jailbreak for old bootrom 3GS users. Later, after iDevices owners pointed out a problem with the untethered jailbreak available for the old-bootrom 3GS, MuscleNerd released redsn0w 0.9.9b9d to fix the old bootrom 3GS issue.

Meanwhile, pod2g had decided to put all his effort on the A5 jailbreak and handed over the task of releasing A4 jailbreak to the Chronic Dev team.

I gave all the details to the chronic dev team so that they can finish, test, integrate and release the A4 jb ASAP, the hacker posted on his blog.

Pod2g overcame a major hurdle last week by resolving the A5 cache issue. However, he is still trying his best to find a bootrom-level exploit in A5 devices, which are built on Cortex-A9 dual core processor. The bootrom-level exploit is a low level exploit that can only be fixed by revising hardware and it is read-only. Apple's A4 was built upon ARM's Cortex A8 CPU which was a single core CPU.

On Tuesday, pod2g beat MuscleNerd to release untethered jailbreak for iOS 5 (5.0.1 version).

And though it was for only non-A5 devices, MuscleNerd was overflowing with praise for pod2g.

It's released! Congrats to @pod2g for untethering iOS 5.0.1! See http://is.gd/dO7hc5 for details (non-A5 devices) MuscleNerd tweeted on his Twitter account.

On the official iPhone Dev-Team blog site, MuscleNerd and his team members gave all details of how to get the new iOS 5 untethered jailbreak.

@pod2g has created a terrific gift for iOS fans - an untethered 5.0.1 jailbreak for non-A5 devices!

Many of you have already been following @pod2g's blog where he’s been keeping everyone up to date on his progress. And so you know that he recently decided to push the button on a release for all devices except the new iPhone4S and iPad2. @pod2g's untether involves two separate exploits and a few other tricks - and since he's taken the @comex approach of doing nearly everything himself, you know his plate has been full these past few months!

A few days ago, @pod2g gave the untether to both the iPhone devteam and the chronic devteam. We've put it into redsn0w 0.9.10 and PwnageTool, and the chronic devteam put it into a Cydia package (the same set of exploits is in all three).

Here are the basic steps for how to get it:

The untether is for iOS 5.0.1 on iPhone3GS, iPhone4, iPhone4-CDMA, iPad1, iPod touch 3G, iPod touch 4G
If you have one of those devices and are not on 5.0.1 yet, update now! The SHSH window is still open for 5.0.1 If you unlock via ultrasn0w or gevey, make sure you only get to 5.0.1 via a custom IPSW! See the guides at places like iClarified.com if you don't know how. Once you're at 5.0.1, use the latest redsn0w 0.9.10 to both jailbreak and untether.
If you're already at 5.0.1 with a tethered jailbreak, you have two choices: either run redsn0w 0.9.10 over your current jailbreak (deselect Install Cydia if you do that), or install the Cydia package prepared by the chronic devteam. The patches are the same regardless of which you choose.
Some of you are using a hybrid 5.0/5.0.1 configuration. If so, do not attempt to install this untether over that setup! You will most likely get into a reboot cycle. Do a sync and fresh restore to 5.0.1 then install the jailbreak untether.

As mentioned earlier, @pod2g has spent months working on all the exploits and tricks in this untether, and many of you may be wondering how you can send donations. Although the iPhone devteam itself doesn't take donations, we thought it was appropriate to provide a link at the end of the redsn0w run for you to more easily donate directly to @pod2g if you wish (alternatively, you can go right here). There's a link in the Cydia package for donating to the chronic devteam for the Cydia version of @pod2g's untether.

@pod2g is now looking for a way to extend this to A5 devices. Because those devices cannot use geohot's limera1n exploit to inject the untether, they require exploits above and beyond those used for this release. Keep following pod2g on twitter or his blog for any progress reports!
Here are the redsn0w download links:

redsn0w 0.9.10b1 for OS X
redsn0w 0.9.10b1 for Windows (be sure to run in Administrator mode)
