  • nick

    can anyone confirm if facetime still works?

  • Grime

    Interesting, but I'm waiting for an unlock, tick tock tick tock.

  • mp3dog

    Step 8 says "Continue to press the home button" but you never mention when it is ok to actually release the home button.

  • Ash

    Grime, Me 2 waiting for Unlock. right now i can use my iphone 4 as ipod touch only. I hope we will get it soon.

  • Good point, updated the steps to include it. Thanks for pointing it out.

  • Macdaddypdx

    Is this the jailbreak that will stay with the device forever, no matter what apple dose??

  • mp3dog

    Sorry, I must have been reading too fast. I see it now in step 9.

  • b3rt619

    Im doing it right now, hope i dont hit any snags…i doubt it though.

  • Jeff

    If I have an iPhone 4 running 4.0.1 that is already jailbroken (via JailbreakMe) can I just upgrade to 4.1 and then use Limera1n to rejailbreak or do I need to uninstall all my Cydia apps and then upgrade to 4.1? I would think I could just upgrade to 4.1 with my phone still having all the jailbroken apps on it because 4.1 would wipe them all anyway, but just wanted to be sure.

    Any insight would be much appreciated!

  • 523

    comon come out with ipod touch 2g support

  • mp3dog


  • b3rt619

    worked perfect!! the only thing was i deleted the l1merain app before i installed cydia on accident, so i had to re-jailbreak it to get the app back. so make sure to install cydia before deleting l1merain. now i just have to fix my phone back to how it was.

  • b3rt619

    yeah that's what i did. i updated to 4.1 and itunes deleted every thing. then i jailbroke my iphone and basically started over kinda sucks but its all good.

  • Jarrett

    What is the home key on a mac? I can't figure it out

  • Jeff

    That's what I figured. Thanks for the help!

  • b3rt619

    its the only button other then power and volume.

  • Jarrett

    Oooooo whoops haha i thought it was talking about the computer. Thanks

  • Eric

    anybody else having problems with rotation to landscape? all my apps will stay in portrait view and not rotate to landscape since the limera1n jailbreak.

  • HH

    i'm stuck with the "downloading cydia" any ideas how it should last.

  • b3rt619

    lol Its all good happens to the best of us.

  • Danny

    Did u set the rotate lock function on by accident? Press home key twice and look for circular arrow icon…

  • If I have a bunch of apps on the phone now (before jailbreaking) what happens to them? Do I lose them? I guess it doesn't really matter as I have backed up the phone before I'm going to attempt the jailbreak but I would still like to know.

  • Dao

    Worked like a charm…having no problem at all in jailbreaking iOS 4.1. I checked my iphone4's firmware after jailbreaking and apparently the firmware was downgraded from 5.13.x to 2.10.04.

    Interesting fact!

  • bhuvan

    I did everything as mentioned here, i am running limera1n, it completes the expoit and then when i restart the phone,there is no limera1n installed… please help

  • MP

    So if I Jailbreak the 4.0.2 iPhone via limera1n I still can't get the phone unlocked yet? Or can I use Ultrasn0w unlock after this jailbreak?

  • Dj

    I don't think so

  • Dj

    Im waiting for the unlock does anyone know if it's possible yet or hen it will be available?

  • Mark

    Anyone know what the timetable is pertaining to the unlock?

  • Gio

    You should back up your iphone via tiny umbrella and just upgrade to 4.1, but YOU won't be able to unlock your phone

  • Gio

    I think it should arrive any time soon, because i've been waiting for unlock on my iPhone 4 for more than 2 months

  • Gio

    Dev team, can u please tell me if I can unlock my iphone 4 from "" You have tham on your site. All the way up on this page. It coasts around $30. Will it really unlock my phone or it's just a scam. I've been waiting for unlock more than 2 months. Please let me know. Thanks

  • Moodi

    yes it is working

  • Snips

    My fones working perfectly after havin jailbroken it….tks to geohot and iphonehacks

  • Grime

    The way I understand it is that the security hole can't be closed, meaning you'll still be unlocked if you upgrade you're firmware or it can be easily patched using the previous method of unlock. Now I could be wrong, and if so please correct me.
    The real problem is for people who use carriers other than At&t. You could update to the newest firmware, and lose your unlock capability because as far as I know there isn't a permanent unlock solution, so you'd still need to be cautious about updating.

  • Grime

    Sorry, please ignore my above post, I used the words unlock and instead of jailbreak. I really wish there was a way to edit prior comments.

    What we need is a permanent jailbreak and unlock, that would be the ultimate solution, but I'm greatful for what we have now, lets just keep or fingers crossed. lol

  • Robin

    Working fine for me under Mac and the iPhone 4 from the german Telekom.

  • dwayne Fox

    I upgraded my iphone 3GS to 4.1 a month ago, I want to know if I will be able to unlock my iphone with this or what do I need to do?,
    Pwnagetool won't help me because i already upgraded? HELP HELP

  • No, it is not possible as the baseband shipped with iOS 4.1 has not been unlocked. PwnageTool will help you preserve the baseband while upgrading to iOS 4.1 assuming you are on a lower version.

  • JJ

    I just did it and is not working!
    "unable to load network list"

  • iOS4

    My take for everyone having issues after jailbreaking. Restore your iphone and run limera1n. Do not back your phone after restore. Make sure you do all the necessary settings including the Cydia updates before you do any backup.

    Most of the issues people are having is due to errors, they might already have in backups or some compatibility issues with some apps.

    On the issue of itunes erasing everything from you iphone when you upgrade, not restore. I have always had success in having all my program intact after using the update feature in itunes. The only things i lose are the, jailbreak, cydia and all cydia apps. Crack apps still remains but crashes when trying to open.

    Someone can also try updating rather then restore and report the findings

  • if 1 59 00 yes

  • James

    I had some trouble when i finished updating my firmware with tiny umbrella. It wouldn't kick my device out of recovery mode. I googled and answer and found out that its a problem with the new version of tiny umbrella. I downgraded TU to 4.1.4 and it went smooth from there.

  • Gohans

    I am tempted to update to 4.1 and jailbrake it but i don't want to give up the TetherMe feature on my 3GS 4.0. Do any of you know if TetherMe runs on 4.1?

    thank you.


  • Mark

    are you on a new iphone 4 meaning the firmware version is 02.10.04?

  • Leo

    any idea when will be possible to unlock 4.1 new baseband? I got an iphone 3gs but already came with 4.1 and baseband 5,14,02 bootloader 6.4, I was able to jailbreak it but unlock is not possible, any way I can do it? dates? hope? please!!

  • Budda

    What about PPC mac users? This is intel only.

  • Kallias

    Did anyone else loose WiFi after the jailbreak? It looks like I'm connected to the network, but I'm not getting any data through it…? Had to install Cydia via 3G.

  • Dan

    i use Mywi and that works perfectly if that helps!


    No you won't. The jailbreak only allows you to install 3rd party software. The unlock is done on the baseband and so far, nothing for the new 4.1 firmware. But keep hope as there are rumors that it might come soon.

  • shroom911

  • Bullfrog

    Uhh, how about trying 10 seconds instead

  • Hey guys just tried this 7 times. Keep getting to the step after it's jail broked where you have to launch limera1n. I click on the icon and the app flashes up with the logo up the top then crashes. Not matter what each time I jailbreak it, this keeps happening…

    Any ideas? Mine was JB on 4.01 prior to this and worked perfectly. So now I'm stuck because I can't install cydia.

  • marcos

  • Dutzy

    can i jailbreak my 3gs ! updateing at 4.1 via itunes?
    it's jailbroke with spirit 3.1.3

  • dwkazzie

    the limera1n JB worked perfectly on my 3GS. I had JB'd using jailbreakme a few months ago, and then undid it when I upgraded to 4.0.2. I regretted it, so I was happy to see another JB option.

    Just follow the directions exactly — it could not be easier.

    Also, I knew nothing about GeoHot, other than his "name", so I was floored to see he's only 20 years old. the only thing I could do at 20 was shotgun a beer. freaking amazing.

  • To-my-AA

    Yeah it seems to be happening to me.. The DFU (step 8) screen is up but won't go on.. I held the home button.. firstly for a long time.. then for 10 seconds (after resetting it). and the same. It seems it's stuck on that part.. Any thoughts?

  • simon

    i am using an iphone 3gs version 3.1

    How long does the phone take to restart???

    Everything was fine up in till it asked me to restart my phone… the apple icon has now been on for about 20 minutes.

    Can someone please help?

    Thank you.

  • simon

    OK…. I just wrote the previous message for help.

    I am still trying to restart my iphone but continue to get only the apple icon in the middle of the screen.

    The apple icon has been on for over an hour now and the phone feels quite hot the touch…

    Could I have just totally fucked my phone up… woopsy.

    I am using itunes 10.

    please help guys! thanks

  • simon

    OK… Now iTunes is telling me that in order to restore my iphone i have to update it to the latest version on iphone software which would then not allow me to jail break my phone!!!

    arrrrgggghhhh!!!! any hints from computer wiz's out there!?

  • simon

    Thanks Mate! But I am just worried that in doing this itunes is going to want to update my iphone to a newer version which will then not allow me to jailbreak the phone… sorta like im damned if i do and damned if i dont!

    plese let me know if that is so…cheers jasa
