How to Untethered Jailbreak iOS 5.0/5.0.1 on iPhone 4, iPhone 3GS, iPod Touch 4G, iPod Touch 3G, iPad1 Using Redsn0w 0.9.10b1 [Tutorial]

iPhone Dev Team and Chronic Dev Team has released Untethered jailbreak for A4 devices which includes iPad (First Generation), iPod Touch 4G, iPod Touch 3G, iPhone 3GS, iPhone 4, Apple TV.

From iPhone-Dev Team:

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!


pod2g hacker behind iOS 5.0/5.0.1 Untethered jailbreak has warned user to not update their devices when iOS 5.1 out in feature.
