iOS hacker pod2g has posted a very enlightening synopsis of how he was able to pull off his 5.0.1 untethered exploit. Citing Apple’s blocking of the exploit methods used prior to iOS 5, he details the alternative methods used for the 5.0.1 untethered exploit and subsequent jailbreaks.

Apple has fixed all previous known ways of executing unsigned binaries in iOS 5.0. Corona does it another way.

Thus, for Corona, I searched for a way to start unsigned code at boot without using the Mach-O loader. That’s why I looked for vulnerabilities in existing Apple binaries that I could call using standard launchd plist mechanisms.

For those of you interested in the low-level workings of the latest untethered jailbreak to hit iOS 5 devices, we highly recommend you check out pod2g’s analysis on his blog.

        Okay, here you go. I hope you’re joking though. I mean, even Sherif Hashim said the same thing on Twitter:@sherif_hashim
        most of the comments people left on @pod2g ‘s latest technical blog post made me feel really sick, lot of ungratefulness and impatience 🙁

        Here are some the comments that you “missed” out.

        lol….he just made a blog update and a long one that is with no mention of the A5……Anyone believing he is still working on the A5 is a ******* morron.

        Boring!! work on A5 – iPad 2 PLEASE

        This Info is defenetly unusefull for the most People
        We all want the A5 jailbreak
        Why dont you Post some news about that?
        Cant understand it….


        He cant jailbreak it but will not Update that info
        If people are still donating

        We have been patiently waiting for a long time now for the A5 jailbreak, It seems as if he is just waiting for more money he started with donations and now he is getting quite a bit of cash from google adsense ads running on this site. OK he does need rewards for his hard work however I advise you people do not donate until we have the A5 jailbreak. Do not even check out this blog just follow him on twitter as he is getting to greedy with the ads provided by google, Therefore he is not going to release it anytime soon. People that donated don’t even get a update. Please do not donate until we have the jailbreak.Last year we had the same situation with chronic dev team and their greenpoision they took so long and wanted all the publicity and then geohot came out of the blue and released his much more stable limera1n, And geohot asked for donations once he published the fully downloadable jailbreak. Please only follow pod2g from his twitter on!/pod2g

        No I have not donated anything, Why should I without having the jailbreak?
        And why does it concern you if people are impatient? People donate their cash and want to see results at least be updated on the status.

        Does anybody give a ***** about how it works!?!?!?!?

        What a nice man. We buy him a ******* car and he gives us what we had back on 4.3.3, an untethered jailbreak. How about you give us we don’t have. An iPhone 4s jailbreak!! BINGO *******.

        And as i said before…No one trusts you anymore…

        Shut the **** up Joe. No one asked for your **** ******* *** to get on pod2g’s blog and **** his **** so **** off back to the foster home you came from.

        Oh I see where your coming from. I don’t have a 4S. I don’t watch his twitter and read his blog daily.

        This is all none-related to his explanation what his post was about.

        Yeah, ur right. A lot of people don’t give a sh** about how the jailbreak works.(I happen to)

        But what you said had nothing to do with his post about the exploit.

        You basing what you said on your general opinion of what @Pod2g is doing and how he is doing it.

        Now once again. Please point out the “selfish” comments in his blog post about the exploit. You still didn’t give me any.

      • Kok Hean

        If bashing an iOS hacker online just because he didn’t release his free jailbreak for the A5 devices isn’t selfish, I don’t know what else is.

  • Still no 4S jailbreak. 🙁

  • I have an iPhone 4S, and I am happy to wait for them to find an exploit. I have background in Coding knowledge, and I wouldn’t even know where to start. I hope these people that are expecting the jailbreak also donate some money to the guys putting in the free time to bring these exploits to you.

    There will always be iPhone exploits but as we move further along into each new model it will just be harder to obtain, with Apple almost being forced to add new features much like the ones that people use in Jailbreaks there may be a time when its not needed, or just not as much as its needed right now. I have a feeling that Apple will launch iPhone themes next, which is still one of the major reason’s I jailbreak my iDevice, if they also add a quick launch settings like SBSettings, I will prob never JB again.

  • wtf is up with the people there? “A4 jailbreaks are walks in the park for these developers not worth any donations” Seriously? Ungrateful bastards. All they care is for A5 jailbreak.” I don’t care about A4 updates, gimme A5 now!!!” Sometimes i wonder how our civilization will react if we ever find life off of Earth…….

    • Probably kill it. Like many movies seem to imply.

  • to be frank. some people are really ridiculous, they sound like pod2g owe them the JB. sigh!

  • Why do I feel like he shouldn’t post how he created the might read it and get a little smarter

  • Still no 5.0 untether for A4 devices?

    • Why not upgrade to 5.01? if you have an A4 iDevice?

      • Does it make the battery life worse? Or is that A5 devices?

  • If its this difficult to find a bootroom level exploit for dual core A5 processor which is just in two of the current apple products, I wonder how much more difficult it will get with the new quad core A6 processor which will be used in iPad3 and iPhone5. The wait for an untethered jailbreak then will be even longer.

  • Should we 4S Users stay on 5.0 or should we update to 5.0.1 before 5.0.2 is alive to JB later ?
