  • 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.

      It doesn't matter if you post or not, I've been on plenty of sites to figure out an issue real quick without posting on their forum, that doesn't mean I'm not part of the "community". We have Guide sections on this site that jailbreakers can come on and look at without posting anything, that doesn't mean they're not in the community. I think if you're trying to make your phone better or customizing it to your liking then you're part of the community.

      The main reason people jailbreak is to steal apps. I know there are the "noble" people here on the forums, but you're the minority.

      Apple should spend it's time creating a way to lockdown apps, and then they could throw in the towel on the cat and mouse game.

      After all, that's what this is about. The 30% they're missing from the cracked apps....

      You're right, It would stop apple from losing lots of money, and lower the amount of jailbreakers. Plus we would be able to lose many of the "immoral jailbreakers"

      If that was the case then developers on Cydia would be making zip.

      I think this kind of generality is ugly and pure bias, please lets be intelligent, Two main reasons to jailbreak

      1. To use the GSM phone on another network like TMobile
      2. To use apps like Bite SMS (Apple would never approve it as is)
      and
      3. To use themes and Lock screen enhancements

      To use for "Stealing?" I and other Jailbreakers should take offense to this crap you posted.................


      No they are wrong and its offensive, most do not do it to steal.
      Not most, but still a big number

      Steve, you are using the resources of this forum so therefore you are part of the community. You posted. That makes you part of the community. Haha so in other words I really have no idea what you were getting at with that comment but by posting it you became part of the community. I never said the MMi community I said the iDevice community. So I guess this is welcome to the community.

      Whatever happened to jailbroken iPhones being able to be used to crash cell phone towers and bring down the network infrastructure?

      Just like drfp said. I paid for iblacklist even though I'm sure it's available on ********** now for free because AT&T does a crappy job of it and charges $5 a month whereas iblacklist is $12 for a lifetime license and does a phenomenal job.

      Same with mywi for those of us lucky enough to be grandfathered in with our unlimited data plans as opposed to at&ts crap tethering and insane monthly cost. AT&T has 2 choices, improve their network to the point that the tethering cost is actually worth it or drop the cost of tethering significantly.

      Wait, are some people here saying that if Apple wanted they could stop jailbreaking? That's like saying they could make an OS immune to viruses and hacking. A Mac ISN'T immune to hacking, people. Maybe they're more secure, but it's not like that's the only reason they hardly get viruses. Another reason is there's not as many Macs to steal data from as PC's. iDevice consumer rights rebalancing will come to an end when all talented white-hat (meaning non-malicious) hackers leave the scene.

      what was your phone doing? I just restored mine yesterday. I had folder enchancers too but i didnt redownload it yet.

      not saying its not possible but.... the only thing I have read was that phones with infrared/beaming and wirelessly could be hacked into that way
      What? That's what I said, the main reason Macs are more secure is because there are less of them to hack, meaning less of banking data and similar incentives for hackers. I was using it as an example because jailbreaks are kind of like viruses in the way that they inject unauthorized (just non-malicious) code. So saying jailbreaks can come to an end - which is what I interpreted some posts as saying - is like saying Apple can make an unhackable OS.

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.
      What are you talking about? There's nothing wrong with jailbreaking, the only thing I can think of is that if you jailbroke a company phone, and the employer doesn't understand the full potential and purpose of jailbreaking (unless you work for apple)

      I'm sure people would counter security issues with jailbroken phones with MSS and Cydia. For instance, there was a cydia tweak to patch up the 4.0/4.0.1 PDF exploit used in JailbreakMe that was patched by apple in iOS 4.0.2/3.2.2

      What? What was the real danger? I have never heard of a problem with PDF's

      You see I do not buy that these found exploits are a true threat.
      All these years I think most of this stuff is hype, there are only a few people in the world who even know how and what to exploit ( Like Apple developers), this means that they are easy to catch, no?

      The only things Apple seem to care about all this time is allowing more features ( I can't believe they are still "Developing" them I think they had a list of possible features and add them a few at time ) by taking time releasing the features they could then see what the JB did so they could focus on the real reason for Upgrades, "Security" to close the exploits used by JB. To apple the real threat is Cydia, open platform, IOS is meant to be exclusive (Monopoly) to Apple control and the App store.
      Well, Star (the name of the jailbreak) gained root access on your phone, executed unauthorized code, and installed a program. Imagine what could happen if the hackers weren't playing nice with that security hole? They could literally delete core operating system files and make you restore. Since they could gain root access and write data, I'm sure they could remove it. Not to mention they could probably beam data including password caches to their servers (just guessing here). Short and to the point, they could most likely do ANYTHING since the jailbreak compromised the OS to run unauthorized code, there's no limit to what they could do. Maybe they could even write a key logger for it and steal very sensitive passwords and information.

      Yeah. Meaning someone could use something like Star, but instead of installing Cydia it installs a key-logger (something that sends every key you type to the hacker's server). Depending on the range of accounts you manage and data you send, this can lead to anything from messing with your Facebook to identity theft.
