After seven betas, One GM and another performance improving update (which itself has two beta 1/2), iOS 5 hasn’t ever received an untethered jailbreak yet. Many users have to make a tethered jailbreak of their idevices if they wish to enhance their experience with apps and tweaks from cydia, now it appears that the jailbreaking community is getting closer and closer to an untethered jailbreak for iOS 5 as one of the famous hacker sent out an update regarding its progress.

The update on iOS 5 untethered jailbreak comes from pod2g. Few days back, There’s nothing else to work on, on the iOS 5 expect making it untethered jailbreak so the Chronic Dev Team may have achieved this untethered jailbreak of iOS 5 and may release it as soon as iOS 5 is released.


From pod2g:

Hey jailbreaking friends, I’ve found a bug that can untether iOS 5. Don’t expect a release soon, but I’m gonna work hard in it.

No details about the bug has been given, but, however, it is a userland exploit like the five userland exploits which were announced by p0sixninja at this year’s MyGreatFest.These userland exploits – unlike bootrom exploits – are software-based and, hence, would be available for all iOS devices, including iPhone 4S and iPad 2 (as was shown by MuscleNerd of iPhone Dev Team), on the version of iOS which has the userland exploit.

Comex’s JailbreakMe which was based on a PDF exploit in Mobile Safari on iOS 4.3.3 was the last userland exploit-based jailbreak, the main disadvantage of an userland exploit is that it can be easily patched with software update where as bootrom exploits acnot be patched unless hardware is revised.

iOS 5 is currently jailbroken using Redsn0w or Sn0wbreeze but it’s tethered only. Tethered jailbreak means you’ll have to connect your device to your Computer every time it reboots so people don’t like tethered jailbreak at all.
