Untethered iOS 5 jailbreak is the holy grail of jailbreaking as of now. That too, since the reports say this could be a userland exploit (more on that later), this would mean you’ll get to jailbreak untethered iOS 5 devices – like iPhone 4s and iPad 2. So what’s actually cooking in the jailbreaking community?
A recent tweet by a member of the Chronic Dev Team – something like the iPhone Dev Team, yes – that has been working on bringing out tethered and untethered jailbreaks for long, has been making its way all across the cyberspace. The tweet says the guys have found a bug which can lead to an untethered jailbreak. This would mean that the end of days for all the hype and hoopla for the iOS 5 jailbreak.
A tethered jailbreak for iOS 5 was already released sometime ago. Although at first the jailbreak seemed to work only on the developer version of the IPSW file (the betas), the iOS 5 tethered jailbreak from redsn0w was made to work good on almost all the devices like iPhone 4, 3GS and iPod Touch. That was however tethered, which means every time you reboot your iDevice, you should have it connected to the jailbreak software on your Mac/PC. If you did not do that, your device would be bricked (would stop and not function at all as it connects to the iTunes).
The untethered iOS 5 jailbreak would relieve all that trouble. You wouldn’t have to connect your device to the system every time you restart / reboot your iPhone / iPod. To users who are not much bothered about the code, about the development etc., this would mean the best way to jailbreak your iPhone / iPod. As simple as it seems, untethered is what every jailbreak-hacker tries to get to – that’s the final step in jailbreak.
There was a semi-tethered jailbreak for iOS 5 though – and that was also sometime back. A semi-tethered jailbreak would let you reboot your iDevice but with limited capabilities – and would prevent the iDevice from bricking.
The untethered iOS 5 jailbreak is said to be an userland exploit. Now, if that is true, then by all means that’s a huge good news. The userland exploits are software-based, which means the jailbreak (untethered) for iOS 5 would work on all the devices running iOS 5 – which includes iPhone 4S and iPad 2. If that is the case, we can expect an iPhone 4S jailbreak in the works.
As far as the time of release goes, nothing is known. It would take the hackers quite a lot of time to clear out all the issues with the jailbreak – they’d probably launch a development version of it, and then they’ll have to fix the bugs and then release the final version. It may take months before the actual release – but judging by the speed with which the whole jailbreak community has been working over the few weeks, it looks like an untethered iOS 5 jailbreak would be out soon.
