The Dev Team reported that it is safe to update your iPhone to OS 3.0.1. After updating your iPhone to the latest 3.0.1 firmware, you can run the latest version of RedSn0w and point it to firmware 3.0.

Since the 3.0.1 doesn’t update the baseband, you will also be able to unlock your iPhone using UltraSn0w via Cydia (for iPhone 3G and 3GS), and you will also be able to run RedSn0w on your iPhone 2G to unlock it by following these steps.

My latest tutorial on how to jailbreak your iPhone using RedSn0w still works and I suggest you check it out if you’re not sure on how to update and jailbreak your iPhone.

Note that in order to jailbreak, you will have to update to 3.0.1 in iTunes first, which will remove all your jailbreak apps.

For more detailed information about jailbreaking and unlocking, I recommend you check out the jailbreak page and the unlock page of this site. It is updated with the latest info.

    Once again thanks for the Up to date info Sebastien, just updated…. but still dissapointed APPLE is not doing anything quicker to address the Battery issue…

    • SMYLZ

      Dude…..Battery life? You are carrying a phone/computer in your pocket. Quit bitching. If you want the battery life of a Nokia, go buy one. The iPhone battery lasts a day and a half for me. Go cry to someone who cares.

      • VistaUSer

        @SMYLZ ……. Please watch your comments ! I like millions of other users have seen a decrease in Battery life that is caused by the 3.0 OS… If it lasts a day and half for you, than good for you….. I like many others are experiencing battery depletion….. So next time you decide to be rude to others just Shut the Fuck Up instead !


        SMYLZ, you my friend are a fucktard

      • VistaUSer

        Go Fuck your mother ! and film it with your 1 day and half battery iPhone PenisBreath !

  • manofsteel1982

    what is the latest redsnow update for the 3g? thanx

  • @manofsteel1982 the latest RedSn0w is 0.8 and you can find it from the downloads page.

    • Ashley Scott

      But 0.8 is only for the 3GS isn’t it?

      It doesn’t work with the 2G. I had to revert to 0.7.2 to jailbreak/unlock 3.0.1.

  • @Ashley Scott – interesting. That might be a bug in RedSn0w 0.8. Since it wasn’t developed to jailbreak/unlock 3.0.1, it’s not completely compatible with it. The Dev Team said it will release an update sometimes. This should fix this issue.

    • Ashley Scott

      It got as far as ‘waiting for reboot’ and just sat there.

      I went through the process 3 times before reverting to 0.7.2, which just worked flawlessly.

      I’m holding off updating and jailbreaking my 3G until the situation is clear.

    • mehran

      has it released an update about it? i have a 2g iphone and have the same problem as ashley.

  • Jackzilla

    im having an issue with jailbreaking a 3gs with 3.0.1. RedSn0w quits halfway through the process! anyone else having this issue?

    • Jackzilla

      yay, actually, after two DAYS of trying to get this to work, I finally was able to rejailbreak!

      I am new to jailbreaking and was wondering is it still possible to sync with itunes? or does itunes detect Cydia and delete it?

  • Rn3sto

    There should be some way to upgrade without removing the cydia apps. O_O

  • Henry

    My battery was fine until this morning. Now it won’t last 30 minutes!!! Help!

  • GTA Charlie

    Jailbreak with redsn0w 0.8 has worked perfect for me, but when I install any package through Cydia that needs to restart the iPhone, it gets stuck and I have to restore. Any possible solution?

  • james

    Does anyone know if Skype still works after this latest jailbreak and what do I need to install to get it to work? I am holding off on upgrading to 3.01 until i get the confirmation as I use skype quite a bit. Thanks and hope someone can provide confirmation

    • VistaUSer

      Everything is working fine….

    • iPhoneUser

      Yes Skype is working on 3.0.1

  • raya

    As i am unlocking my iphone, When i select the ipsw firmware (in the first step) It doesnt work! It says “Unable to identify specified ipsw”.
    I made sure i have the right ipsw firmware but nothing works.

  • klear6

    Ok does my avatar work now? If it does its much better. Alright guys I am writing a guide on how to jailbreak a 3gs w/ 3.0.1 OS by taking bits of information and putting them together. when I am finished it should be pretty foolproof and anyone is welcome to a copy of it.

    • VistaUSer

      Sebastien already has one on here, and it’s about as simple as it will get….

    • Donna

      Klear6, my daughter took my 3g jailbroke/unlocked phone back home with her to germany. So, I went to my Apple dealer and purchased a new 3gs with 3.0.1 pre installed. I am using redsnow 8 and can not get passed the “waiting to reboot”. No matter how many times I pull the USB plug and reinsert. Please help I miss having my jailbreak apps

      • wisamkashour

        I am having the same problem with redsnow and purplera1n. it is driving me crazy. I do have the 3.0.1 on 3gs

  • Jackzilla

    Anyone else currently having problems with Cydia starting up? It keep saying there is some error while “downloading releases” and then it quits out..

  • Windows7-64BIT_User

    I was not able to jailbreak my 3.01 but had no problems at all jailbreaking 3.0. The redsn0w.exe program would “error”. I did not have the error with the same version of windows 7 & iPhone 3.0. Tried multiple easy fixes (reboot etc ) and none worked

  • Andy

    There was a problem with the battery overheating/losing change in hours, in some iphones after 3.0 update they replaced mine at the beachwood store at legacy village in ohio

  • Chase

    yeah im giving up on this whole jailbreaking thing…. ive downloaded the files for redsnow and my firmware for my iphone 3.0.1 well 3.0.0 and it wont let redsnow even find the s*** but anyways yeah if anyone has an idea holla

  • whosays?

    Not giving up yet but I’m having the same problem as Chase. Can’t find the .ipsw in the firmware .zip file. I think I’m missing a step somewhere.

  • Chynababe

    Hi Whosays. i think maybe your problems is that you are looking for the ipsw in the zip file. I think you will find it is the ZIP file. Bythis I mean that if you download the firmware with cirtain programs it downloads it as a zp file instead or keeping the file extension as it should be. the IPSW. Try downloading it without download manager or use Firefox and it should download OK. I hope this makes sense as Im useless at explanations but maybe one of u guys can explain it better.

  • aelredf

  • len7

    There’s an obvious reduction of battery life for Iphone 2G after upgrading from 2.2.1 to 3.0. The battery life doesn’t even last half a day. Have installed bossprefs and any adjustments made does not help in restoring the original battery life. Does anyone know if this is resolved if you jailbreak it to 3.0.1?

  • len7

    My bad… bossprefs does seem to help with the battery life after you initialize it on the iphone 2g 3.0

  • Lawal Abiola Moshood

    I forgot my phone unlocking code and i mistakenly locked it and iphone was disabled..I jailbreak it and unlock it…Now,i upgraded my iphone 3G 3.0 with itunes 9 and now it says,activate with original sim without pin…Please,what do i do?tell me…
