Limera1n iOS 4.1 Jailbreak Released by Geohot


Update 1: limera1n updated for iPhone 3GS units with new bootrom.

Geohot announced he was going to release his universal jailbreak limera1n on 10/11/10, a day after the Chronic Dev Team was going to release their greenpoison jailbreak.

Looks like Geohot has decided to release his jailbreak a day early limera1n is now available for download (Windows only). Here are the details from

some people still don’t have windows
beta iOS versions aren’t supported
uninstall in limera1n app doesn’t work, you can just delete the directory, i need regression testing

Download for Windows

According to MuscleNerd, SHAtter is now going to be delayed:

SHAtter will be held back now, so it’s not the worst possible scenario. Who knows, maybe SHAtter can even be improved

iPhone3GS & iPhone4 ultrasn0w unlockers: stay away from today’s limera1n. Wait for PwnageTool, else you’ll lose unlock

We haven’t tested this yet, but if you have, be sure to let us know how successful you are with Geohot’s limera1n jailbreak. I’m going to wait for PwnageTool as usual. Can’t go wrong with official jailbreak tools from the iPhone Dev Team.

You can also check out the iPhone Wiki for more info on limera1n.



  • Well after i did a back up of my iphone i tried it and its running good. I got an Iphone 4 running 4.1

  • Kenny3535

    lucky u !! i tried it on my iphone 4 and it didnt work 🙁 !!

  • make sure when u click make it rain that you read what you are suppose to do. You need to hold the power and home button until it tells u to release it

  • Trungiie

    i just used it on mine and worked flawlessly , go cydia!

  • Kenny3535

    yea i did !! its just when the limera1n logo is suppose to come up i get a apple logo again ??

  • well i saw it once so when ur iphone is on u should see limera1n and open it install cydia reboot amd u should see cydia

    only way to remove the limera1n icon is to install cydelete

  • well i saw it once so when ur iphone is on u should see limera1n and open it install cydia reboot amd u should see cydia

  • Fateh

    worked great on my iphone 4

  • ive done it two times.. followed instructions on box.. then it boots apple logo.. then nothing….

  • Kenny3535

    r u on the latest version of itunes ???

  • you know what, actually no – im using my old pc laptop (usually use macbook) so I will try that, my bad!

  • Kenny3535

    haha same thing happened to me !! LOL

  • Kenny3535

    worked for me after updated itunes !! YEAH !!

  • Trungiie

    unlock works for anyone? my 4.0.2 works but the 4.1 doesn’t work

  • Kotlon,Tigan

    jailbreak and cydia work on Iphone 4 with Ios 4.0.2 but ultrasn0w dosn`t unlock firmware 01.59.00

  • jailbrkr

    i jailbroke successfully

  • man my pc is slow!! finally did it.. it rained!!! woot

  • ultrasn0w does not work on 4.1 unless you wait for PwnageTool

  • Nick

    Has anybody successfully jailbroken using this on a mac running Windows in VMware?

  • Works great. I had to install the latest iTunes (because I never use my Windows machine) before it would go past “Waiting for device…” but otherwise, took 30 seconds to JB and a reboot.

  • I might sound stupid but .. I’ve bought so many apps on cydia when I had my 3GS, then upgraded to IP4, and ofcourse finally able to JB.. how do you get cydia to recognize your purchases? it recognized one and the rest seem to say I need to purchase..

    any help?

  • Nice work. I will wait for PwnageTool. No Windows box around here!

  • Good thing my Mac has bootcamp windows xp lol. I will JB tonight when I get home tonight.

  • Mhadd071

    Hey the jailbreak doesnt seem to be working with iPhone 3Gs MB model, on 4.1 i tried everything? i tried it on differen iphone4s and it was working fine just the iphone 3gs didnt work

  • Anonymous

    a lot reports that it isn’t working for the 3gs

  • Matt

    What is the difference between this and the upcoming shatter jailbreak?

  • Matt

    I also have a 2nd gen ipod touch and would like to know if it would work with it, it’s a non mc model.

  • Trungiie

    Well then any idea if i can restore and rejailbreak with pwnagetool?

  • roadcarver

    What does unpatchable mean? Does it mean its jail broken for good?

  • Yen Chung Ryan Liu

    what does it mean only for windows??

  • J Warwani

    I am new to this entire thing, so please be patient 🙂
    I’ve got iPhone 4 with iOS 4.1 (8B117). My baseband is 02.10.04.
    The phone is locked to Fido, and I want to jailbreak it and use in on Rogers. I do have a PC. From what I’ve read, limera1n does not let you unlock as well as jailbreak. Do i have to wait for something else to unlock? If so, what? And when is it expected?
    Can I jailbreak using this in the meantime, then get the unlock later? What do you recommend? Thanks in advance.

  • Kakarot

    well when i first tried it… I could not see cydia, so I rebooted… I still could not see cydia, so then I used spotlight to find it, upgraded cydia… and I could see it, smooth sailing from there on out!

  • Kizzyed

    So far so good…I4 running on 4.1 FW, no problems to be reported..yet…Thanks Geohot!!!!!!!!!!!!

  • so is greenpois0n delayed or its still being released as planned?

  • It’s going to be delayed, and re-programmed to use the limera1n exploit, so
    SHAtter can be saved for later.

  • Thanks Gary. Would you be able to suggest whether I should wait for gp or I can use limera1n.
    Also I got my iphone 4 with fw 4.1 so will i be able to unlock it with limera1n or i will have to wait for an unlock.

  • Anonymous

    Curious……. will ultrasn0w still unlock if you use limera1n to jailbreak but your phone isn’t currently unlocked right now?

  • I would personally wait for PwnageTool.

  • Anonymous

    Hey Gary, is your download link the latest BETA3 release? Thanks!

  • I just did my 3Gs… really easy

  • Yes. Geohot’s permalink structure for the download remains the same:

    Always download from to be sure. 😉

  • Bulishor

    Tried it on my iPhone 4 and it goes through the process, says the jailbreak is done and then I can’t find the limera1n icon. Rebooting does not help. Searching for it doesn’t bring it up. Definitely not working 100%

  • TeenWolf

    Jailbreak worked. FaceTime not working. It worked before I used limera1n. Just keeps saying waiting to activate.

  • Obuksus

    Hi guys, this might sound silly and am a noob at this but can you jailbreak an iphone 4 dat is not yet activated ??? If no. How can i activate without a micro sim ?

  • Keseto

    Same thing happenend to me. I have tried several times and same result. Dammit!

  • Worked perfectly fine for me on the first attempt.

  • Worked perfectly fine on my iPhone4 on the first attempt.

  • Canadiansnow

    Here is what I did to unlock my iphone 4 on 4.1 using the new jailbreak

    First this is only for IPHONE 4!!!!!!!!

    Second follow the steps laid out on this website(, make sure you get this right the first time because there is no going back after!!!

    Third use limara1n to jailbreak instructions i found here(

    and there you go now you should have a jailbroken iphone4 that can still be unlocked!! You are welcome from ice cold Canada!!

  • if you’ve already updated to a stock 4.1 through iTunes, your baseband is updated and you’ve therefore lost your unlock (possibly forever.)

  • Anonymous

    Wait for the PwnageTool to be updated for limera1n so that you can unlock.

    It shouldnt be too long of a wait.

  • Anonymous

    Mac users cannot use limera1n to jailbreak right now. Only those running Windows 7, Vista, XP can

  • Guest

    I did the jailbreak on my iPhone 4 running 4.1, and I cannot get Cydia to install. It just says “respringing, please wait”, and the app doesn’t show up. What’s going on there? Any suggestions?

  • Anonymous

    Hey guys. I’ve jailbroken my iPhone 4 using limerain. First thing I did was to get 3G unrestrictor to use FaceTime over 3G. Well it doesn’t work. Lol. It keeps telling me that I have to connect to a wifi connection. Anyone else have this issue using limerain? Or maybe I’m doing something wrong? Anyone have ideas? Thanks guys. 🙂

  • Xetal

    Geohot Just jailbroke my Iphone 4 in 20 seconds with both of my eyes closed.

  • Guest

    I got my iPhone 4 with fw 4.1 so which means the baseband has already been updated when i received it. So how will I be able to unlock the phone.

  • Put Your Junk

    got my ipod touch 4 jailbroken with limera1n…. but not when I exit out of spotlight, it consistently puts the ipod into safe mode. a bit annoying.

  • Knguncle3

    Question: I sync my iPhone with MAC. If I JB using Limera1n in Windows, can I still sync to my MAC after JB?

  • Elmasri

    how do i jailbreak my iphone ?

  • Bulishor

    OK. solved the problem by updating to the latest version of iTunes. The limera1n icon showed up and installed Cydia. I had to reboot to get Cydia to show up but after that I was good to go. Just thought I’d post so others can use the jailbreak as well.

  • iPhoneOnRo1ds
