iOS 6 Beta 3 Jailbroken Already

hypnosec writes "Apple launched the iOS 6 Beta 3 just a couple of days back, and the redsn0w team has given out a jailbreak for the latest version of iOS 6 already. The only downside is that this is a tethered jailbreak, which means you will have to make sure your phone is connected to the computer whenever you need to reboot it."

      You don't know how wrong you are. There are so many things I think Slashdotters would appreciate knowing about the iOS jailbreak process:

      1) The "Tethered" (easy) jailbreaks only work on pre-2011 devices.
      2) 2011 and later device can only be freed using "untethered" jailbreaks.
      3) "Untethered" jailbreaks using Apple's copyrighted code usually happen first, but are not distributed because they would be subject to DMCA takedown. The hackers want to do this legit.
      3) Making the last untethered jailbreak (whether for the "tethered" pre-2011 devices or the other ones) actually involved what appears to me at least to be a spectacularly complicated process:

      http://pod2g-ios.blogspot.com/2012/01/details-on-corona.html

      TL;DR is that untethering iOS devices is spectacularly difficult, especially due to the fact that at least one of the best jailbreakers has been hired by apple.

      It's substantially more complicated than that. If it were as simple as every buffer overflow being exploitable in this way, then jailbreaks would come thick and fast after every release.

      With iOS you have:

      (a) stack is never executable, so all payload must be ret-to-libC style
      (b) consequently, because user space address layout is randomized with about 8 bits of entropy, you have to find a way to leak address of a symbol, or else find some more sophisticated exploit
      (c) even if you defeat above, you still only have typically gained executable control over a restricted user account
      (d) now you have to trigger a kernel exploit from restricted process space sandbox OR

      (d)+(e) break out of the sandbox or gain root with another userland exploit in order to be able to trigger the kernel exploit, which may depend on functionality accessible from root only

      Anyway you get the idea. My hat goes off to pod2g and co for their dedication.

    So in other words they managed to jailbreak iOS 6 beta 3using a previously known exploit which exploits things that are hard-coded... How is this exciting news? If you exploit hardware you should be able to jailbreak any OS on there, its simply just porting some software. To make it even less exciting this is a tethered jailbreak which means its useless for nearly everyone.

    As an AppleTV owner I care. The hardware is pretty decent, and the add-ons are where the real value is (xbmc for example).
    I'm not interested in apple's locked in system and really unhappy with the cat-and-mouse game of apple trying to "close" the system. I had an auto-update break my xbmc once, then i spent a lot of time trying to fix it. flashing the appletv involves sending a signature to apple to confirm this is a valid IOS to load.

    This whole 'dmca' type stuff is nonsense. if i bough the hardware, why do you go out of your way to prevent me from doing what i want? If you want to behave like this, then RENT the hardware so you still own it. Why sell me something, then attempt to force me do do only what you want with it?

    Why jailbreak an iOS device?

    My job involves benchmarking web pages loading on a celular connection. Real connections have very high variance, so that tests run a minute appart can not be compared. I run dummynet on the phone to simulate a cellular connection in a controlled, repeatable way. Running dummynet requires jail-breaking the device on iOS 5 and below.

    As a user, I see no reason to jailbreak, and I would never use a jailbroken device. As a developer, I need to modify low level settings to understand how decices behave.

    Most of the JB-ers have never touched Installious. In fact, if the Dev Team could block that thing from being installed, they could. JB-ing != pirating.

    Want to know the reason I JB? Simple. There are a number of apps that make life easier. That, plus I like full control of my device. Simple things like tarring up some files or having a very secure stash for my gpg keys (where I can pipe files through a ssh to the device for signing/decryption) that are doable with a UNIX prompt, but no apps.

    As for JB apps, here are a few:

    1: 3G Unrestrictor -- I pay per gig for bandwidth, if I want to download a multi-gig app, I should be able to.

    2: iBlacklist. iOS6 has rudimentary functionality for dealing with unwanted callers, but there are some numbers which you don't want to hear or read texts from, period. Having an app for that is a lot cheaper than getting a restraining order.

    3: AppBackup. There is no way on iOS to copy off a game's save files, delete the app, then later on, reinstall the app and have the save files at the ready. Yes, a few apps store their files in Documents, but that is the exception.

    4: Backgrounder. Woodall's Maps needs to have foreground access to complete its large downloads, so either have to keep it in the foreground, or use an app to make it think it is there.

    5: Protect My Privacy. iOS hands out contact info freely to any app that asks for it. This protects against spamming of contacts.

    6: Firewall IP. You would be SHOCKED at what apps try to connect to. Way too many targeting, tracking and ad sites.

    So, don't assume all jailbreakers are pirates. Most of us actually pay for what we use.

    "Why sell me something, then attempt to force me do do only what you want with it?"

    Are you serious?

    Because that's what they advertised it to do.
    Because that's what they have to guarantee it do.
    Because that's what they have to support it to do.

    Letting you do whatever you want with it undermines their ability ensure it does what it should during their legal warranty period and beyond. What do you think happens when an infrastructure update breaks on your device because you've screwed with it - and you bitch and moan all over internets !

    Having said that, I am strongly of the 'open hardware' view but I do understand their business problem - definitely not a apple fanboi so don't go there

    Ideally they really need to sell 'open' hardware at a premium (for lost revenue stream that otherwise subsidises the hardware) with no warranty/no support and let you do whatever you want with it - basically the PC hardware model.

    Who's to say they don't already? Knowing how to "jailbreak" is the cost of entry. Look at the OSX86 world. It's not like every OS update they're making it impossible to do with installation keys and a phone home. If you make it so that anyone can do it I'm suddenly going to get support calls from my aunts who read all the cool stuff you can do with the iPhone. Toss it behind a 'jail break' and they suddenly automatically remove the warranty issues, idiots that don't know what they're doing, etc.

    Frankly, I wish jailbreaking an iOS device was impossible. Why? Because it might actually stop people from considering iOS devices as worth buying, because of what they can do when jailbroken. As long as its easy to climb over the walls the gardener builds around his garden, far fewer people care that the walls are there in the first place.

    As users, we should have the ability to run whatever damn software we please on the hardware we've bought. And no, we shouldn't have to hack our devices for that privilege. Yes, even software that the platform vendor doesn't approve of.
