  • Jailbreak Detection API Dropped from iOS 4.2


    Apple has quietly dropped a jailbreak detection API from the latest iOS 4.2 update. This feature was only introduced six month ago. It is somewhat puzzling that Apple would choose to remove this feature from the iOS so soon after introducing it to the platform. Apple and the jailbreak community have been playing a game of cat and mouse ever since the App Store was first introduced in 2008.

    The jailbreak detection API is part of Apple’s mobile device management (MDM) API that was released back in June with the introduction of iOS 4.0. The detection API works by asking the operating system if it has been compromised in any way. Jailbreaks usually change operating system files to gain access to the iOS, so that users can install non-approved apps. Apple routinely issues updates to circumvent these exploits requiring jailbreak developers to find new ways of gaining access to the iOS.

    For most iPhone users, jailbreaking an iOS device is just a way to install unapproved apps, install customizations and in general, have more control over their devices. For enterprise users, where maintaining tight security is a top priority, jailbreaking an iPhone can be a real headache for network administrators. Some corporations have created their own ways of checking the integrity of a users iPhone by attempting to carry out actions that a non-jailbroken iPhone would not be able to perform. If the iPhone is able to operate unauthorized actions, the iPhone in question can have its access to the corporate network disabled.

    The fact that Apple has dropped jailbreak detection should be a good thing for the jailbreak community. It would appear that jailbreak developers have become so adept at countering any security measures that Apple can come up with, that there is no one solution for maintaining a closed operating system. This can only be good news for the jailbreak community, unless of course, Apple has something new waiting in the wings. Lets hope not because I would hate too loose all of my favorite jailbreak apps.

      That survey is incorrect.. Where did they get the info from? Online? Only asked people who go to their website.. what if its a dominant non-jailbroken users go their. Not only that but those statistics are over a year old before the release of the ipad. And not to mention all those companies that wont allow their employees to jailbreak. So take away all those iphones and your probably left with a much high substantial number. MMI is for jail breaking and we have now 778,654 people. Now i'm willing to bet 99% of people have their iOS w/e it is jailbroken or why be on this site. So your telling me apple isnt going to lose out huge if jailbreaks go away. Dont kid yourself and iphone costs $699 multiply that by 778,654 people. Ha! not to mention that but i own 2 iphones and an ipad. Legit those would be both on the ebay within 10mins if i knew jailbreaking was existent. But apple knows that as much as i do. Now all we need to do next is find out which namer tag is steve jobs using on MMI.

      It isn't really that hard to detect a jailbreak. Apps from the App Store have been doing it for a while

      Saurik has said many times the number is close to 10%, which is still tons of iPhones.

      This in a nutshell is why i believe jailbreaking actually still survives with apple demonizing it. They secretly condone it.

      From what I hear a solution may exist, but it's very private. That crowd has kind of moved on...

      It's always possible that Apple can lock us out, that is their goal after all.

      What Percentage of iPhones Are Jailbroken? Less Than 10 Percent? | iSource

      Lastly, here is my response because I felt like it:

      Thats why we jailbreak so we can do the things we want on iDevices, but you ask the average iPhone user and most of them have never even heard of jailbreaking and/or dont want to cuz they think its unsafe and messes up their device.
      Since we're pointing out where people are wrong. First, here is where YOU are wrong. He said "a lot" not "most" "the majority" "all" or anything else that implies a more than 50% group thereof.

      Second, posting a link to a single survey that could have any unknown number of honest/dishonest participants, an unknown variable which is how many people frequent that site that may happen to be those that either don't jailbreak or don't know how is in and of itself, inaccurate. Add that to the fact that even 9% (which is less than 10% if you are mathematically-challenged) of all the iPhones out there is STILL a lot of iPhones. Millions, to be exact. That doesn't even include people like myself and many others that own more than 1 iPhone as well as people who own iPads that are jailbroken which use iOS and thus fall under the same umbrella.

      Third, if you specify the iDevice "community" as the actual owners of the phones that is one thing but if you define, as I do, the iDevice "community" as the people who frequent forums asking for help with their iDevice or talking about their own personalization then I am VERY sure the jailbroken higher is upwards of 80% or 90% because otherwise you likely wouldn't be on the forums.

      Yeah but apple gets all their iOS feature ideas from Cydia tweaks, so they would be lost witout jb devs.

      actually they were playing cat and mouse way before the app store was introduced. I purchased my first iphone in June of 07. It was jailbroken by september. The appstore was not introduced until the iphone 3g which was a year later

      I don't think the idevice community is only people wh frequently post in forums, it's everyone. That's why it's called a community. And I've seen quite a few surveys showing a percentage of people who are jailbroken and it's always been between 6-9%. More than that many people know what jailbreaking is, but dont think they need it. Tons of people I know jailbreak only for the "free apps". If I could get something like SBSettings without jailbreak, I wouldn't be doing it myself

      The reason I only consider the community to be those of us that post on various forums help with our jailbroken or non-jailbroken devices is because that is what a community does. Those that don't ask for help, talk about it, or contribute aren't really part of the community in my opinion. We always talk about what the iDevice community wants and we can gauge pretty well what we feel the community wants based on posts and popularity of new ideas or changes that should be made that are posted on forums. That is why I consider the iDevice community to be those that at least discuss ideas or ask for help or try to provide solutions, etc. not just everyone who happens to own an iphone, ipad, or ipod touch.

      That is the problem though. The surveys don't say where they got their information from or how many people were involved. The smaller the sample size you get the less likely you are to find one of those people being a jailbreaker unless you surveyed people who almost exclusively frequent MMi for example in which case you'll probably have 10 out of 10 or 9 out of 10 being jailbreakers. Plus depending on where these people took the survey FROM(home, office, etc.) they may not have answered truthfully because their internet traffic could be monitored. It might be a far-fetched idea but it still probably has quite a bit of truth to it. Either way 5% of iPhone owners with a jailbroken phone is still MILLIONS of people. Furthermore, if people knew how safe jailbreaking is and how many apps are available to enhance their lives that aren't available on the app store then that number would likely go up significantly. The problem here is education of those who aren't jailbroken in the pros and cons.

      Perfect example is my buddy who has a non-jailbroken iPhone 4 on firmware 4.0.1. I recently found out he isn't jailbroken and since I'll probably be getting his iP4 sometime around june when the new one comes out then he let me cache his SHSH blobs for 4.1(since it was past the signing cutoff for any firmware before that). 4.1 still has all the capabilities of running the apps I have on my 3GS with 4.0 on it so I'm not worried. Anyway, after I showed him apps like iBlacklist, MyWi, xGPS, etc. he was sold on jailbreaking and this afternoon I'll be performing the jailbreak for him so he can see how it is done. If people had more information on it then there would be more jailbreakers and Apple would sell more iPhones.

      Just like the gentleman a few posts above me, if I couldn't jailbreak then I never would have bought an iPhone. Period.

      Ok. So this is probably one of the most educated conversations ive had on this website. Considering the first post is always

      I also think many don't jailbreak because they feel that if something goes wrong and Apple knows they have did so then Apple will not guarantee the phone if its still under guarantee.
