There hasn’t been much talk in the jailbreak community regarding progress with either an iOS 5 untethered jailbreak or a 4S jailbreak. But we just received word from infamous iDevice hacker pod2g that, if you’re hoping for either one, stay away from the next iOS update.

Pod2g announced last night that the code-signing bug security expert Charlie Miller uncovered a few days ago could make jailbreaking “dramatically easier.” And since Apple is aware of the issue and will likely patch it in iOS 5.0.1, he recommends not updating…

This makes things complicated for a couple of reasons. First of all, if you’ve been experiencing poor battery life with iOS 5, chances are you’re dying for the update. The new version of iOS is expected to fix the much-talked about battery issue.

Second, if you upgrade to iOS 5.0.1, you won’t be able to downgrade. You might recall a recent report by the Dev Team that explained why there isn’t currently a way to downgrade to previous versions of iOS 5, even with saved SHSH blobs.

And finally, you could be in trouble if you have a device that you haven’t updated to iOS 5 yet. Once Apple releases 5.0.1 to the public, it will stop signing 5.0. This means that you could miss the iOS 5 jailbreak altogether if an exploit surfaces that is iOS 5.0-only.

So, should you update? If you use your device daily, and can’t take the battery problems anymore, you might have to take your chances (you should still wait and make sure the issue is fixed).  All others should stay away, at least until we know more information.

  • Too late!!!!!!!

  • Too late!!!!

    • How is it too late? Apple is still signing iOS5, you can easily downgrade from 5.0.1 still.

    I’m on iPhon 4 with iOS 5 and since I disabled those options for cell tower and clock updates, battery lasts long enough. I finally got a tremendous increase since I disabled 3G. It can be enabled quickly through SBSettings…

  • I miss steve jobs, Tim Cook thinks he knows everything, making updates like crazy, launching new Iphones that doesn`t have much difference from the others at all.. What is he doing to Apple?

    • Anonymous

      Was this a serious comment? Tim Cook has said he knows everything? He’s making updates like crazy? launching new Iphones that doesnt have much difference? Instead of listing reasons why your wrong; next time you should give reasoning behind your comments.

      I don’t want to be a dick…. but fuck dude….. I cant even send a good response to this.

    • Anonymous

      Dude, just SHUT UP. Of course he sends updates (not “like crazy”) to fix issues, so that people like YOU can stop whining. First of all, I don’t think anyone but you said he thinks he knows everything. Second, STEVE JOBS designed and planned the iPhone 4S THE WAY IT IS RIGHT NOW, so if you don’t like it, deal with it, and don’t blame Tim Cook for things that aren’t his fault. And by the way, I wouldn’t consider the 4S something ‘to regret’. I mean, wasn’t it the most sold handheld in years?

    damn, downgrading to iOS 5.0 now

  • Anonymous

    This get’s confusing. So it’s possible to downgrade from iOS 5.0 to say 4.3.3. This is fact as I have done it 3 times so far on my iPhone 4, but once you go above iOS 5.0 there is no going back? Can we get some clarification please.

    • Anonymous

      So far I know is if you update to iOS 5 with latest baseband on it, there is no way to go back to iOS 4 even you save SHSH.

      • I upgraded to iOS 5.0 with sn0wbreeze so my baseband was not updated. The more I read the more I think this only affects the iPhone 4S.

      • Anonymous

        Not true at all. Any iPhone.

      • WRONG !! I am on 4.3.3 again after going to iOS 5 and I have done it several times just like I went from it to 4.2.1 on my iPod .. It seems to me that people are making out they know something when infact they don’t. In my experience I have had no issues at all going from iOS 5 to signed firmwares of 4.2.1 and 4.3.3, I use the signed 1’s because they do not require checking Apple’s or Cydia’s servers which is probably why they work, I don’t know for sure but I imagine a standard firmware with blobs saved is what will not work but it 100% works when downgrading from iOS 5 to lower with a signed firmware file and it takes the baseband with it, again something that people say you can’t downgrade !!

      • Anonymous

        You can downgrade on ipod because there is no baseband on it.

      • I have downgraded 3 times on an iPhone 4. It’s possible. I don’t know where all this misinformation is coming from.

      • @ coejam .. Dude please STFU and stop arguing about it, you are wrong, FACT !! I have downgraded my baseband many times when downgrading firmwares so don’t imply that you know it all and others don’t. No matter what iOS you were on, if you downgraded to a firmware that Apple were still signing you always downgrade your baseband aswell, that is 100% .. I never said the baseband could be downgraded when the firmware you want to go to isn’t being signed and not to mention the fact the reply i posted had fuck all to do with basebands, it was about being able to downgrade firmware.

        You’re better off just not saying anything else on the matter cos you have no idea about what you are chatting. Like Marc Berman said, both he, I and many others for that matter have downgraded with signed firmware many times but I guess us physically doing it must be wrong because you say it can’t be done, douchebag !!

      • From 5.0.1 to 5.0 is what they mean!!

  • I’m still on 4.3.1. with my iPhone 4. Are you sure I cannot upgrade to 5.0 once 5.0.1 is released, even when I saved my SHSH blobs? That puts me in a terrible dilemma.

    • upgrade to 5.0 tethered is not that bad. Unless you preserve some BB.

  • Anonymous

    I dissabled time zones iAds and traffic. I whent from 4hrs on full charge to 7hrs on a charge. I’m staying on ios5. And waiting for the jailbreak. I got 4s on launch day and this is the longest I have been without a jailbreak in 2 1/2 years. It sucks!!!!

  • I’m on 4.3.1 with my iPhone4 currently and do not want to loose my jailbreak, so what should I do now…update to 5.0 and hope that the community will not need too long or to wait for the jailbreak and maybe miss 5.0

    Any opinions?

    • Anonymous

      I would wait, 5.0 tethered is not much fun. I hated it and downgraded to 4.3.3.

      • It’s also a buggy jailbreak, I found my iPhone randomly rebooting itself, hours later i’d notice it was just stuck on the Apple logo which would really annoy me if it did it while I was out and were unable to boot tethered.

      • Use semi-tethered.

  • Anonymous

    if anyone is currently on any of the iOS 5.0.1 betas you can successfully downgrade to 5.0. i just did it

    • Anonymous

      downgrade before it’s too late 😉

  • JB is just part of the game, how about SHSH playback? How can you re-install a firmware when you screws things up? iPhone is pushing me to the other side day after day…

  • Dan

    For me, both my iphone 4 and ipad are on OS5, both jailbroken and my battery life is just fine. I imagine the battery issue is with iPhone 4S. With all this crap, I should of just stayed on OS 4.3.5 lol.

  • How can I save my iPhone 4S Shsh Blob, because TU won’t recognize my device.

    • Anonymous

      Apparently shsh blobs and TU are both redundant on the iPhone 4S

    • Anonymous

      There is no iPhone 4S SHSH blob to save it.

  • Tommy Lee

    somebody please educate me.
    i’m using iphone4, so i’m not experiencing battery issues, and i’m currently on jailbroken 4.2.1 OS.
    so, should i upgrade to iOS 5 and use tethered JB or stay on 4.2.1 ?
    thx be4. 😀

    • Anonymous

      First, I need to know which SHSH you had save on tinyumbrella?
      If not, I suggest you should save SHSH before you do any further.

    • Stay on your 4.2.1 jailbroken iphone 4. So much tweaks and awesome theme which might not work on ios 5

    • Dan

      If I were you, I’d check out a compatibility list to see if all your favorite tweaks are working on OS5. If they are, take the plunge. (as for me, sbs, folderenhancer, appsync, gridlock, perpage, ifile, infinidock, killbackground, sms+, winterboard, nofolderbadges all work so I’m happy)

      Tethered is not so bad and like the article mentions, if you don’t update now, you might miss the jailbreak when they update to 5.0.1.

  • I have a semi-tethered jailbreak iOS 5 on my iPhone 4 and I don’t seem to have any battery issue. What I did is simply turn the battery percentage off. I just learned that having that activated, people are now concern about how much power their iPhone consumes, not thinking on the amount of work they are doing with the iPhone itself. Unless, if your iPhone is unofficially unlock and you rely on SAM for the activation, then I can say it really sucks. My iP3G before consumes more power that the amount of work I am asking it to do.

  • I need help. I have an iPhone 4 still on 4.3.3 and my iPad 2 still on 4.3.3. I like them untethered. I also have an iPhone 4s. I haven’t opened it yet because I’m waiting for the jailbreak. My question is, does the iPhone 4s come with 5.0 straight out of the box. If so, when I try to activate it, will it make me update? The other question is, should I update the other 2 devices since apple won’t be signing 5.0 anymore. It will suck but I want to be able to still Jailbreak my devices. Thanks in advance.

    • iPhone 4S comes with iOS 5.0 out of the box. Stay on 4.3.3 till there is an untethered JB.

    • Anonymous

      Open, activate, and and feel the ios 5.0 on your i4s. If you like it, upgrade your i4 to ios 5 (before apple release 5.0.1). You can go back to 4.3.3 later on, but you’ll miss the untethered 5.0 once apple release 5.0.1

      • If battery problem on iOS 5.0 why would you stay on it? you better stay on 4.3.3 untethered or wait for untethered jb on 5.0.1

      • Well because they just said that there’s going to be a security patch on 5.0.1. So why would I was for an untethered JB for that when there might not be one?

      • Anonymous

        Does the battery problem occurs on iphone 4 with ios 5? I guess you can’t go back to 4.3.3 on iphone 4s to rectify the battery problem on iphone 4s with ios 5, can you?

      • Can I do that with my iPad 2 also? Meaning downgrade.

      • Anonymous

        Yes, you can. But atm there is no jailbreak for ipad 2 on ios 5 (although musclenerd might have it).

  • Thank you, finally an answer to my original question. So the moral of the story is do not go above 5.0 if you intend on going back to 4.XX

    • Anonymous

      No. You can always go back to ios 4 with shsh regardless from which ios 5 version you have. You just cannot downgrade to a lower version of ios 5, say from 5.0.1 to 5.0

    • Anonymous

      Well; yes and no. You shouldn’t go above 5.0 but you should have your iOS 5.0.0 SHSH saved, because as soon as Apple releases 5.0.1 you will not be able to upgrade to iOS 5.0.0.

  • Anonymous

    I’m not blaming you guys at iDB, but too late indeed. I already updated to the iOS 5.0.1 Beta 2. Is there any way I can downgrade from iOS 5.0.1 BETA to iOS 5? Please help, since there is no Ultrasn0w compatibility yet, and I’m stuck with mi iPhone as an iPod. Thanks

    • Anonymous

      You can downgrade to iOS 4.X.X if and only if you have your SHSH saved.

      • Anonymous

        I heard that as of RIGHT NOW I can downgrade with no problem back to Official iOS 5 (no SHSH, nothing). Is that correct?

  • Anonymous

    This is SCARY: “you could be in trouble if you have a device that you haven’t updated to iOS 5 yet. Once Apple releases 5.0.1 to the public, it will stop signing 5.0. This means that you could miss the iOS 5 jailbreak altogether if an exploit surfaces that is iOS 5.0-only.”

    With no untethered jailbreak in the near future, the best thing to do NOW, for all of us jailbreakers, is to update to the buggy iOS 5 and live with the tethered/semi-tethered jailbreak for a while. Very soon Apple is going to release iOS 5.0.1 and if that happens and you are not on iOS 5 you are going to live with iOS 4.X.X for a LOOOONG time and miss all the good things of iOS 5; besides, a tethered/semi-tethered jailbreak is better than no jailbreak at all.

    I’m on 4.3.1 and I cant save my shsh(u can only save 4.3.3 shsh) so I want to update to 4.3.3 and save my shsh then update to ios 5. My question is can I update from 4.3.1 to 4.3.3 ??

    • Anonymous

      If you have 4.3.3 SHSH on your iphone, yes you can update from 4.3.1 to 4.3.3 using snowbreeze.

      • Anonymous

        Is that the only way? because I don’t have 4.3.3 SHSH
        I guess I’ll update to IOS5 and wait for untethered JB

      • Anonymous

        Which SHSH have you saved in your iphone?

  • If this will turn out really bad at least make 4.3.5 a smooth untethered JB.

  • I’m on jailbroke iPhone 4 with 4.1 still. Should I update to iOS5 with a semi-tether or just wait until they release a jailbreak for 5.01?

      Waiting is the best bro. Keep the untether jailbreak with iOS 4.1.

    hi, my question… i have an iP4 running 4.3.3 untethered using gevey sim. i can upgrade to iOS 5.0 preserving Baseband with redsnow, there has been talking about signed 5.0 ipsw (apple signing). my question is IF I ALLREADY DOWNLOADED THE IOS 5.0 TO MY MAC, WILL THE IOS 5.0 ALL READY BE SIGNED ?? ( i haven’t installed it on my IP4 yet)… or i have to instal it to my iPhone to be sign???… and therefore be allowed to stay on 4.3.3 and upgrade when the untethered is available with no problems ???….. thnx in advance!!!!!

  • Here’s an update I got from redmondpie: Update: Developer Zack Whitfield has informed us that pod2g’s bug, which we talked about in this post, is separate from the Charlie Miller bug that will be, according to Pod2g, patched in iOS 5.0.1. Pod2g’s bug will still be able jailbreak iOS 5.0.1 untethered, but it will take longer.

  • I really hope that they have alternative avenues for introducing an untethered jailbreak. My battery life on iOS5 is garbage and I will definitely be updating to 5.0.1

  • Anonymous

    You are safe to update to 4.3.3 using snowbreeze.
    Since iOS 5 is not untethered jailbreak, I suggest you should keep at 4.3.3 for a while.

    • Anonymous

      thank u very much for your respond
      a final question what was the point of saving shsh if I’m not using it while upgrading to 4.3.3?
      I know that I’m asking lot of questions and I apologize for that

  • Chris Smith

    I have a new ipad2 on 4.3.5 so cannot jailbreak, for best chance of a future jailbreak should I update to ios5.0 or stay at 4.3.5 ?

    • upgrade to iOS 5. there (probably) will be no future jailbreak for iOS 4.3.5 so iOS 5 is your best chance.

      • Thank you. I wonder if there are battery issue/other issues with ios5 on ipad2 though before i update?

  • Once ios 5.0.1 comes out there is no possible way to upgrade to just ios 5 from ios 4.2.1???

  • If you have shsh blobs and can go from 5.0.1 to say 4.3.1, then why can’t you go After that from 4.3.1 back to 5.0?

    Isn’t that a roundabout way of downgrading within 5.x.x? Or am I missing something?

    I’m also still on 4.3.1 and was planning to stay there until untethered came, but now I’m wondering whether to take the plunge to 5.0

    • you can downgrade from any iOS 5 version to iOS 4 if you have saved your precious SHSH blobs. but you will not be able to upgrade from iOS 4 to iOS 5.0.0 once Apple released iOS 5.0.1.

  • i’ve got an IOS 5.0 after restoring my old version which was 4.3.5… i really don’t have idea how to rejailbreak again my phone when i try it always says something that my firmware is unsupported… i really doesn’t know this things….
    guys please give me some advice thanks…

  • Sighhhhhhh. Charlie Miller just had to go and reveal what probably could’ve been jailbreaking GOLD right before the 5.0.1 update.

  • Hi. I have iphone 4 that is on 5.0. What should i do? Is there still no jailbreak for 5.0?

  • Hi. I have iphone 4 that is on 5.0. What should i do?

  • Gaby S

    Is it really too late?? Because I’m on 4.3.3 with a 3GS – old bootrom and I keep running into itunes errors when trying to upgrade to 5.0 (no baseband since I rely on an unlock). Is that why the errors? Or could it be something else?? (by the way, I know I’m going into pwned DFU mode properly via redsn0w because it tells me so. I’ve also edited my hosts file to no longer point to saurik’s servers). Thanks!
