Jailbreak iPhone 3G on iOS 4 With RedSn0w

By , Jun 21, 2010

pwnedYou can now jailbreak your iPhone 3G running iOS 4 using RedSn0w.  This version of RedSn0w will only jailbreak the iPhone 3G and iPod Touch 2G.

At the time being the only way to jailbreak the iPhone 3GS on iOS 4 is to use PwnageTool. RedSn0w should be updated soon to jailbreak both the iPhone 3Gs and iPhone 4, so be patient.

According to the Dev Team, “For now, the redsn0w beta release supports only the iPhone3G and iPod Touch 2G at today’s 4.0. It’s still a beta, so you’ll need to let Cydia reorganize, reload, and update after using redsn0w.

This being said jailbreaking the iPhone 3G iOS 4 with RedSn0w is fairly simple.These instructions are to jailbreak the iPhone 3G iOS 4 using RedSn0w. Instructions are the same to jailbreak the iPod Touch 2G.

How to Jailbreak iPhone 3G iOS 4

Step 1: Make sure you have the latest version of iTunes installed (iTunes 9.2).

Step 2: Download iOS 4 for iPhone 3G to your desktop from our iPhone downloads section.

Step 3: Update your iPhone to iOS 4 via iTunes.

Step 4: Download the latest version of RedSn0w from here.

Step 5: Point RedSn0w to the iOS 4 you downloaded in step 2.

Step 6: Select “Install Cydia”.

Step 7: Follow the onscreen instructions.

Step 8: Let RedSn0w do the hard work for you. Once jailbroken, your iPhone will reboot.

That’s it!

Now as mentioned above, this is just a beta release of RedSn0w, which means you might have a few issues. One of the most common issues is that the Cydia icon appears all white. In order to fix this, simply add the following repo to Cydia and reboot your iPhone: http://apt.saurik.com/cydia-3.7.

If needed, you may now unlock your iPhone 3G running iOS 4 by following these simple instructions.

    Guys… whoever you are MANY THANK YOU’s… i followed the instructions very carefully, and indeed managed to Jailbreak my iPhone 3G… It is working flawless now (It has the iOS 4.2.1installed). Now.. I have an iPhone 4 with also iOS 4.2.1… Any suggestions on how to crack the nut out of it? :)

    • jon

  • Help

    I need help can someone simplify how to Jailbreak after I download everything I dont know how to point to IOS that I downloaded from ITUNES. HELP PLEASE!!!

  • asdjkkjc

    actualize mi iphone 3g a ios 4.0..pero cuando ago el jaibreak no melo desbloquea y no puedo entrar en el…cual es el problema????

  • Joanie

    Ok, I got as far as step 5. When I tried to search for the IPSW for my current frimware through RedSnow, I couldn’t find it! Not sure if I’m looking in the wrong place, I checked in the iPhone1,2_4.2.1_8C148_Restore folder but there were no matching files. Should I be looking somewhere else for the IPSW? Help!

    • lewis

      to your comment have u found out why? because im having the same problem?

  • zee

    if i jailbreak my iphone can i use it with a company that dont have sim cards like sprint?

    • squirrelonfire

      I think so but that would be very stupid unless you own an iphone 4 since Sprint already has much better phone than the iphone like the HTC Evo 4G

  • NoSco1187

    Using any redsn0w I’ve been running into the same problem while jailbreaking my 3G running iOS 4.2.1 I selected update to iPad baseband and still same problem, while redsn0w is runnning it freezes when it gets to the “uploading ramdisk” process. What the hell is the problem?

    • Applesux

      Uncheck all options except for “Install Cydia”. I was running into the same problem until I did this. It seems to me that with every “update” Apple releases tech, as little as a year old, becomes “out-dated” to them. Thank you for this JB.

  • Ivy

    I have an iphone 3g and have jailbreaked it, the 4.2.1, but i have no carrier no. Please tell me, what should I do? Tnx

  • Marc

    Follow instructions from 30.11.2010 above, it worked fine for me!

  • dana

    I have at&t carrier already and i dont wanna change it but i just wanna jailbreak it. do i follow instructions all the way at the top?

  • samantha

    I Have tried to get this to work and when i get to the part that says Step 5: Point RedSn0w to the iOS 4 you downloaded in step 2. and then Step 6: Select “Install Cydia” when i drag it to that it does nothing.. what does point mean? do i have to save it to that file i just downloaded or jsut drag it to it?? i havnng problems im new at this and really want it to work !

    • Sonia

      With “point” they mean “choose”. Save the iOS on desktop and then in redsn0w simply choose it when told to. Point is a stupid expression for this step, when choose would have saved time to write.

  • http://google vicky

    how can i have the program with i can download what ever i want?

  • Sonia

    Must have done something wrong. My 3g was jailbreaked before I began doing this. I upgraded it to 4.2.1, then it “closed down” on it’s own. I then followed the instructions and did as it said. Now it’s been stuck on the starter-apple for 30 mins. Sometimes the screen flashes with some color and then right back to the apple. It’s still connected to the computer. What did I do wrong??

  • An0nymau5

    ASDFGHJKL!!!!!!!!!!! I cannot get this to work…redsnow starts up and i choose the iOS but it says “unable to recognize specified IPSW” ASDFGHJKL HELP ME! I REALLY WANNA JAILBREAK MY PHONE!

  • pinglebart

    Hi.

    I did all the things exactly as described.( done alle the other versions fine) but now my phone won’t work. The process ended with a white square up in the left corner of the iphone screen and when I tried to turne it of it won’t go off. (I know how to take it off). It is stuck with the apple logo and won’t go off or further. I guess I have to wait for the battery to die… any help would be nice. I

  • Joe

    Hello. I already have IOS 4.0.2 and do i still need to update to the next one? and does Red Sn0w know my iPhone is plugged in? HELP!! Plz..

  • Ka

    • Shanna

  • janu

    • crapologist

      Redsnow is a piece of crap that’s why. Obviously, the RS dev team didnt fully and extensively tested their “crap fix” before releasing this version out to the public. POS

  • fatman

    Can any one please help, I have try to jailbreak many time follow the step posted above but when the phone restart, it just keep light up the apple logo and hang there…any one have clue please help

  • Justina

    would this apply to my problem – just updated to 4.2 on itunes, and now the phone is stuck in recovery mode and on itunes it says that it doesn’t support my SIM even though theyre from the same company.

  • rogster

    folks
    i downloaded the redsnow software from iphone-unlocker-pro.com but there is no sign of any ipsw when i extract the files from RedSn0w zip file. help pls? this is driving me cookoos.
    thx

    • hayden

      hey im having the same problem have u found a fix for it yet ? iv tryed downloading the firmware so many times and it still wont show up in redsnow

  • Drumheadnyc

    I have no clue what firmware I am on… I need some help, I just got a used 8g 3g iphone. I only have a tmobile sim. When I connect to itunes it says my iphone sim is not compatible so I can not see the firmware version it’s on. I’ve tried to jailbreak it but it doesn’t complete and from what I’ve read it’s due to the wrong firmware versions.

    I’ve tried to install different firmware versions during the jailbreak process (depending on which directions I follow.)

    The iphone is useless at the moment. I can only use the emergency 911 dial feature. Or I can restore via itunes and let it install the image, but I still don’t know what version it’s using.

    Any help would be greatly appreciated.

    Thank you in advance!

    • Sahota

      hey guys, ive followed the steps as above but when I extract the files from the IOS 4 download there is no file in there that is saved in .ipsw format. step 5 says to select the firmware in redsn0w but how can i select it if there is none in the file i downloaded.. however there are many other random files which i have no clue what they are, is one of them files the one i need to use in step 5?? help please.. thanks.

      • Msd

        sahota
        The file you download should be renamed from .zip to .ipsw and follow the steps

      • hayden

        im having the same problem and how do u change it from zip to ispw?

      • msd

        using your mouse right click on the file and select rename and change .zip to .ipsw
        good luck

  • Leela

  • john

    I have an Iphone 3g 16gb. i upgraded to IOS 4.0 and jailbreaked with Cydia. Since then, the phone is running very slow. Does anyone know how to fix this problem? Thanks

  • Q

    I have the same problem.its stuck on waiting for reboot the whole day. I cannot even turn on the iphone. Its like dead

  • chazyd

    I bet all of you having problems are on the updated firmware which apple has cracked the jailbreak. You can’t upgrade your firmware ever if you want an unlocked Iphone. No jailbreak works with the 5.14 (I dont know the exact firmware version)firmware. It has to be the firmware starting with a 3.

  • mannerohardy

    Q u need to press and hold button sleep + home button together until the logo show up ;)

  • mightcrash

    DO NOT DO THIS!!!!!

    I jailbroke my iphone 3g, 4.1 firmware last night, worked fine until this morning where it was turned off; since then it’s been hell. My phone wont get past the apple symbol, hard resets don’t work, and an itunes reset would work, but because its redsn0w, my itunes doesn’t recognize it. IT’S A BAD IDEA. now i basically have no phone…..

  • lansed

    this is one of the reasons I don’t like tethered jb’s, other than the inconvenience of the boot but things like safari and cydia don’t work until the tether has been complete.

  • sally

    I was having a lot of trouble jailbreaking my iphone 3G. It would always get stuck on the waiting for reboot screen. Turns out it was my timing of pressing the buttons. I had to start pressing the lock key as soon as I pressed the next button. Once I did that it all went to plan!

  • http://mindhunt.com.ua Vadim

    thank a lot!
    I made all as was written here: NOW_UNLOCKED says: November 30, 2010 at 3:42 am

    The same thing happened to me! The trick is to hold down the home button on step 3 for a few more seconds, even after the screen changed.

    HINT: This worked for me better when i had restored my iphone to factory settings before actually going through with it all. Somehow it just worked better!

  • Michelle Williams

    if i upgrade my iphone 3g from version 3 to ios 4 will it restore to factory settings and will i need to have it jailbreaked again? does that make sense?
