It’s a busy and exciting time for the jailbreak community. In the last couple of weeks we’ve seen the iOS 5.0.1 untethered jailbreak for A4-based devices go live in the form of RedSn0w, PwnageTool, and The Chronic Dev Team’s Corona tool. Moments ago we announced that the security expert known as pod2g expects to drop the untethered jailbreak for iPhone 4S and iPad 2 users next week.

Now is the time to update to Apple’s latest firmware, iOS 5.0.1. Even if you rely on an UltraSn0w unlock, you should update as soon as possible before it’s too late to get the untethered jailbreak on 5.0.1.

Joshua Hill, a.k.a. p0sixninja, is the frontman for the Chronic Dev Team. Hill recently tweeted a reminder that jailbreakers should update to iOS 5.0.1 before Apple releases another update and stops signing 5.0.1. Hill has also confirmed to iDB that the upcoming A5 untether for the iPhone 4S should work on both versions of 5.0.1, so 4S owners on the first version don’t need to worry about updating to 5.0.1 again to have the most recent build.

Check our Downloads page for direct download links to specific iOS firmwares.

In case you forgot, Apple recently stepped up its game with the way it handles iOS updates, thereby making it more difficult for jailbreakers to jump on the bandwagon when a new firmware is seeded in iTunes.

iPhone 4 and 3GS unlockers should be cautious of updating their firmware in this situation. PwnageTool will actually allow you to upgrade to iOS 5.0.1 and preserve your baseband, so feel free to update with that Mac-only tool to save your baseband and get the latest untethered jailbreak while you still can.

If you’ve been holding out on updating to the latest version of iOS 5, there’s really no reason to not take the plunge now. With tools like iFaith and TinyUmbrella, you can always save your iOS device’s SHSH blobs and downgrade to a previous firmware when Apple closes the signing window. It would be especially wise for iPhone 4S and iPad 2 owners to save their SHSH blobs right now and update to iOS 5.0.1.

As long as your blobs are saved and you’re on iOS 5.0.1, you’ll be ready for the A5 untethered jailbreak when it drops. You won’t be hindered by a new iOS update, and you’ll stay one step ahead in the infamous cat-and-mouse game between Apple and jailbreakers.

    like i said before apple can do what ever they need to do but im very sure that wont stop the jailbreakers.

      Of course nothing Apple does will stop jailbreakers, but if you’ve been following the jailbreak landscape at all lately, you’ll definitely notice how much more time it took to figure out a way to untethered jailbreak. Cat and mouse game won’t stop, it’s just getting more and more difficult.

  • iPhone 4s update to 9A405 or 9A406?

    • Anonymous

      Same crap but I would go with 9A405 .

    • A5 untether for the iPhone 4S should work on both versions of 5.0.1

  • well i guess this answers my question on the previous blog. will do tonight! i just wish i could preserve the BB on my 4S for a future unlock

  • Anonymous

    I have an iPad 2 4.3.3 untethered but the SHSH blobs for 5.0.1 are already saved within Cydia. Should I still update to 5.0.1 or just hold on to the JB since I have blobs saved for 5.0.1?

    Will also save SHSH using Tiny Umbrella as well, but just wondering if the update MUST be done.

    • Update! SHSH is useless, for now.

    • Anonymous

      No you should update to 5.0.1 because you can’t downgrade with saved blogs on the A5 chip. They just tell you to save the blobs so if they make a tool you will have them.

    • @lilgreenguy…if you don’t update and Apple push out iOS 5.0.2 you will not be able to update to 5.0.1 at all once apple stop signing it..tinyumbrella will not help you at all …Apple sign a ticket now on iOS5 for firmware like baseband ticket… So in other words don’t update keep your 4.3.3 jailbreak ..update to 5.0.1 and wait for this new jailbreak…or try and update to 5.0.1 and get 5.0.2 after apple push it out and get no jailbreak at all..

      • Jeffery Chan

        can try restore option method, option can select the 5.01 firmware?

  • So I should? Update my 4s to 5.0.1????

    • Yes!

    • “Hill has also confirmed to iDB that the upcoming A5 untether for the iPhone 4S should work on both versions of 5.0.1, so 4S owners on the first version don’t need to worry about updating to 5.0.1 again to have the most recent build”.

      I would like to know the same. The above paragraph confused me. I’m on 5.0 (9A334)

      • Basically all that meant is that both builds of 5.0.1 (Apple has technically seeded two) should work with the upcoming untether for the 4S. (The second build of 5.0.1 was only released for the 4S anyway)

      • Thank you Alex. I’ll upgrade tonight.

      • There is 2 iOS 5.0.1 9A405 and 9A406 ..the last one is ment to fix sim card errors on the 4s …I updated my i4s on the 1 of jan with OTA update and my device is on 9A405 …

  • iOS 5.0.1… When it is jailbroken, imagine the battery drain then! If iOS 5.0.2 or 5.1 resolves that issue, I’m updating no problems asked. I’d sacrifice a Jailbreak for my Battery life any day.

    • If you got a battery drain have you tried to restore you device and set up as new ?

      When I did this on my i4s my battery drain was gone on 5.0..

  • SO EXCITED – this will be my first jailbreak. Can’t wait!

  • Is it possible to save an iPhone 4S’s 5.0.1 SHSH as of now? Do the tools support it?

  • so should i upgrade or no upgrade

    • Upgrade before its to late lol… plus untethered jailbreak is avelible on 5.0.1 and u can preserve baseband so it’s not a big deal if u do… But it is if you DONT lol

  • I pointed this out on here on the 1st of jan ( what twitter got right / wrong post ) so glad that you’ve posted this now before apple push out 5.0.2 …save your blobs with tiny for 5.0 and update to 5.0.1…

  • Pod2g has put this on twitter as well

  • TU has now been updated to get 9A406 blobs now as well

    What was the tweak to disable the little red notification badge on the Settings app? I remember iDB did an article on it but I don’t know what to search to find it…

  • Anonymous

    Does this caution apply to iPhone4 also? I am stilIl at 4.x because of several reasons, one of which being battery issues with 5.x. Is 5.0.1 considered a good upgrade for iPhone 4?

    I am confused by conflicting information about being able to go to a specific firmware using saved shsh blobs. If I update now, and later need to do a restore after 5.0.2 comes out and Apple stops signing 5.0.1, what would be my options?

    • It’s pretty much completely 4S issues. Though I do suggest looking at our location services settings after you upgrade an turning off the time zone switch. Though I’m not havin any issues on 5.0.

    • Well here is my experience. I was running iPhone 4 GSM 4.3.3 jailbreak for six months with no battery issues at all. Go to bed at 100%, wake up with over 96%. Decided to upgrade to 5.0.1 after pod2g’s warning on twitter and jailbroke using Redsn0w. Went to bed that night with 100% and woke up with 80%. For some reason I decided to add Mail to my notification center the next day and woke up the next morning at 31% after going to bed with a full charge!!! Turned off every single option in notification center, turned off Location services and wifi, and the battery still sucks. I don’t care what any of you people say the 5.0.1 battery drain is REAL and you need to decide if having 5.0.1 jailbreak is worth having your battery turn to crap on you. To me it is unacceptable and will be downgrading back to 4.3.3 until Apple actually fixes the problem, screw all the new iOS 5 features, I don’t need em’.

      • I also have a iPhone 4 GSM, on 4.3.0, and am concerned about battery drain as well. Anyone else want to chime in with their thoughts/experiences? Thanks!

      • Anonymous

        Is the battery drain issue applicable to iPad 2 also?

        Talking about battery issues, my iPhone 4 battery is already acting up with only a few hundred charge cycles to it (the other day it was dead from 33% overnight, while on airplane mode). However, I am concerned to go for warranty because I might end up loosing the unlockable baseband. What a fix!

    • Anonymous

      Just to be clear on what I was asking above, the question is on what happens if you have to restore the firmware after 5.0.2 comes out. Naturally iTunes would insist on flashing 5.0.2, but will you be able to do a custom restore and choose a 5.0.1 firmware, even though Apple stopped signing it?

  • Daniel Billing

    But TU says its too late to save 5.0 shsh blobs??

    • So what ..this jailbreak is for 5.0.1 on the A5 chip…you don’t need all shsh’s
      When a jailbreak is out for 5.0.1 are you going to need blobs for 5.0 ?

    • Simon Valenzuela

      Make sure that ‘Request SHSH From Cydia’ is unchecked. I also unchecked ‘Set Hosts to Cydia on Exit’ and it worked for me. Hope this helps.

  • morgan karlsen

    Hi… I’m wondering about something. My number one reason for wanting a jailbreak for my 4S, is to unlock my device. I am currently on 5.0 9A334, 1.0.11. Can someone tell me if I’ll ruin my chances to unlock if I upgrade? I’ve tried to skim through all relevant comments and articles, but I cannot seem to find a resolute answer. Therefore I am hesitant to upgrade, although i gather time maybe short. Can someone please give me a straight answer. Am I understanding it correctly, that there is no jailbreak for 5.0 at all? Morgan

    • I’m no authority on this however Ultrasn0w will not unlock the iPhone 4S baseband. It will only work for 3GS and 4 if the earlier basebands were preserved. The 4S baseband is way to late even if you are still on 5.0.

    • You can call your carrier they will unlock your device for you…you will still need to pay your contract if your on one….your carrier might charge you though but it will be unlocked for ever..

  • Anonymous

    That’s it. I’m giving Apple one month to fix the battery drain, then I’m buying a Galaxy SII. I’ve had enough of this cr*p. Today I woke up and my iPhone 4’s battery was draining WHILE it was plugged to the wall. The jailbreak community should feel free to investigate this issue as well. The only thing that was making me keep my iPhone were the apps/games, but I don’t find myself enjoying them as much anymore. So I guess it’s time to move on to a better/more mature/get-what-you-pay-for phone.

    • jose castro

      dude u might just have a faulty cord lol, i had one when iphone 4 came out. get a new cord if not then that sucks for u

    Does stitching SHSH blobs to firmwares not work for A5 chip devices?

  • How do I keep my 4S baseband?!

  • Hey, I’m running 5.0.1. (9A405) on my iPhone 4S. I don’t need to do any upgrades right?

    • no you dont its the same version both so the jailbreak will work either way

      • Thanks a lot brother!

  • hi i recently updated my iphone 4S from 5.0 -5.0.1 build 9A406, so i tryed to upgrade using the ios 5.0.1 build 9A405 and now its upgrading to that version and build im curently running an iphone 4S on Sprint this is normal because its the same version IOS and its still in signing right?????/

    thanks for the info regarding the blobs. will be updating tonight after i jb my bro’s OG iPad.

  • Just updated to 5.0.1…

  • Yep

  • Mark Griffioen

    I have an iPhone 4 running iOS 5.0 with tethered jailbreak. I really don’t mind the tethered jailbreak, as I’m around a computer most of the time. Is there a compelling reason to update and rejailbreak?

    • Byron de Waal

      Yes, you will get a untether?

  • I’m iphone 3GS user with iOS 4.2.1. Should i update to 5.0.1? Will it slowing down my i3GS performance? Help me….

    • My question exactly, Rizky. Let’s hope iDB chimes in… -Jeremy

    Apologies for being thick, but the upgrade to 5.0.1 mentioned here is the official iTunes upgrade? So I will lose my iPad2 JB temporarily?

    • Anonymous

      yes. I just updated mine in preparation of the A5 untether. Sucks to lose the 4.3.3 JB, but if it indeed comes out next week, you’ll be ready to go.

  • moe

    Hmm.. my iPad 2 is jb’d on 4.3.3 but I don’t have SHSH for 4.3.3 saved. Should I upgrade anyways?

  • can anyone tell me why i keep getting error code 21-24 when trying to update to 501? everytime i try it just fails and goes into recovery mode :/ iphone 4

  • OK, please forgive me if you think this has been answered before, but I’m seeing a bunch of conflicting and confusing responses so I’d like to get an answer for my specific situation.

    I have an iPhone 4, currently running 4.3.3 jailbroken. I have my 5.0.1 blob saved on Cydia, 5.0 and 5.0.1 blobs saved on the device (and on dropbox) via iSHSHit, and 5.0, 5.0.1, and 5.1b1 blobs saved on my PC via Tinyumbrella. I also have the 5.0 and 5.0.1 software images downloaded.

    Am I to understand that even with the software and blobs available locally, I will be unable to upgrade to 5.0.1 jailbroken once Apple releases 5.0.2?

    (I had been holding off on updating until an untethered JB became available. I guess that happened while I was away over Christmas, so I’ll probably go ahead and update anyway, unless there are any compelling reasons (apart from battery life) to stay on 4.3.3)

    • Well, I bit the bullet and updated to 5.0.1. Had trouble with a couple of incompatible tweaks that caused the springboard to go into safe mode all the time, but after I found and removed them it’s all working fine. The only remaining problem is that iScheduler keeps losing its list of scheduled tasks and I’m waiting on a response from the developer.


    am using iphone 3gs.. jailbroke it … ios 5.0.1… default icons vanished…!!!! plzzz help…!!!! 🙁

  • Jon Etkin

    I’m in the same boat as you, however, I think I’ve understood this now so far. The compelling reason for upgrading to 5.0.1 is for 4S and iPad2 users only. This is because although they can save their SHSH blobs with Tiny Umbrella along with all the other iPhones and iPad1, there is still no way to downgrade 4S and iPad2 devices, even if you have the SHSH blobs because the 4S and iPad2 have the A5 chip.

  • Sorry for the disjointed post. Getting used to the interface.

    I’m happy to be told if I’ve got it wrong, but I have seen a video of an iPhone 4 being downgraded from 5.x to 4.x but that was an iPhone 4 and not an iPhone 4S. i.e. an A4 chip rather than an A5 chip.

    Before I update my iPhone 4s to 5.0.1, will it change my firmware? I am currently on 1.0.11.
    What is the best way to update, over the air or through iTunes? I want to jailbreak, when available.

    Anyone else had this problem — I went to update to new iTunes and iOS 5.0.1 (jailbroken 3gs, 4.0.2) and it’s gone into recovery mode and won’t even restore. iTunes gives me an error 21, which is supposedly about my antivirus software, but I’ve uninstalled that and still no-go. Also tried to restore from a laptop and no-go. I’m about ready to go to the Apple store… any ideas first? It’s a brick for now.

  • I have my 4s running 5.0.1 (9a405) on sprint. Saved SHSH Blobs. This device is ready for Jailbreak.
    I have my iPAD 2 WIFI ONLY running 4.3.3 and Comex’s Jailbreak. Saved SHSH Blobs. Do i just upgrade to 5.0.1 using Itunes, loose my current Jailbreak, save my new SHSH Blobs, and Sit tight and wait till the new Jailbreak is released? I am on the right path?

  • Damn I knew this shit was gonna happen… Just because I wanted to have a jailbreak I went from ios 5.0-5.0.1…. And now I suffer from the battery drain problem that I didn’t have ios 5.0 🙁 this shit sucks fucking balls 🙁 I uching hate it that I hat to update and they made me believe a jailbreak was going to come out for IOS 5.0 and 5.0.1 not only for IOS 5.0.1 🙁 suck

  • Those who depend on ultrasnow to unlock, its better to restore iphone 4 to 5.0.1 using snowbreeze to preserve the baseband at 01.59.00 and then untether it using corona.. works perfectly..! AT&T phone running on viettel!! woohoo!! ios 5 with all the glory of jailbreaks!!and dont forget to save shsh blobs! no point using tiny umbrella to verify it since apple still signing 5.0.1!!!! and trust me..battery life improves quite alot for iphone 4!!oh ya..besides that..snowbreeze hacktivates your you dont have to bother having the original sim to activate it!!!!

  • Can I just OTA update to 5.0.1 or is it best (safest?) to download IPSW file (e.g from idlb) and restore w/iTunes?

  • I have an iPhone 4 and I’m currently jailbroken with IOS 5. When I upgrade to 5.0.1 will I lose all my tweaks?

  • I dont understand what to do if I have i4 with 01.59.00 that unlocked how to update without losing unlock. I dont have a Mac.
