How To Perform Untethered Jailbreak On Your iPhone 4, iPhone 3GS Running iOS 5.0.1 Using Redsn0w

Jailbreak iPod Touch On iOS 4.2.1 Redsn0w

iPhone Dev team has just released a new version of Redsn0w, which finally allows iPhone 4 GSM, iPhone 4 CDMA and iPhone 3GS users to perform an untethered jailbreak.

In this guide, we will take you through the step by step procedure to perform an untethered jailbreak on iPhone running iOS 5.0.1 using Redsn0w.

Here are some important points to note before you proceed.

  • This guide is meant for iPhone 4 and iPhone 3GS users. iPod touch users can checkout this guide and iPad users can checkout this guide.
  • If you’ve performed a tethered jailbreak on your iPhone running iOS 5.0.1 then checkout this guide to convert it to an untethered iOS 5.0.1 jailbreak.
  • Important note to iPhone unlockers: Please don’t use this guide directly if you want to preserve your iPhone’s baseband. Follow our step-by-step guide to preserve your iPhone’s baseband first.
  • Redsn0w 0.9.10b5c does not support iPhone 4S currently, but pod2G is working hard on it. We’ll keep you posted.
  • Please note that jailbreaking your iPhone may void your warranty and hence proceed with caution and at your own risk.
  • Please do not forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone.
  • If you’ve jailbroken your iPhone then you can use jailbreak apps such as AptBackupPkgBackup or xBackup from Cydia to take a backup of all the jailbreak apps and tweaks so you can reinstall them easily after successfully jailbreaking your iPhone rather then installing them individually. However, if you’re moving from iOS 4.x to iOS 5, it may be a good idea to reinstall the jailbreak apps to avoid compatibility issues.
  • After the jailbreaking process is complete, do not forget to checkout our article on tips to keep your iPhone secure.
  • Please ensure you are running latest version of iTunes i.e. iTunes 10.5 or later.

Update: Please note that some readers are reporting issue with iBooks after jailbreaking their iPhone.

You can follow these step-by-step instructions to jailbreak your iPhone 4 and iPhone 3GS with the assumption that you’ve already updated your iPhone to iOS 5.0.1 (please note Settings –> General –> About –> Version should be 5.0.1):

Step 1: Download Redsn0w 0.9.10b5c for Windows from this link and Redsn0w 0.9.10b3 for Mac from this link and save the application in a folder named “Redsn0w” on your desktop.

Step 2: Double click the Redsn0w zip file and extract the application to the Redsn0w folder. Navigate back to the Redsn0w folder and launch the Redsn0w application.

Step 3: After launching Redsn0w, click on the Jailbreak button.

Windows 7 users should run the exe in Windows XP compatibility mode (right-click on the Redsn0w exe and select Properties, then select the Compatibility tab and select Run this program in compatibility mode for Windows XP). Windows XP and Windows 7 users should run Redsn0w as ‘Administrator’ (right-click on the Redsn0w exe and select ‘Run as an Administrator’).

Step 4: You will now be prompted plug your iPhone to the computer and switch it OFF. Follow the instructions and click on ‘Next‘ to move to the next screen:

Step 5: You will now need to put your iPhone into the DFU mode. Redsn0w will take you through the necessary steps:

(a) Hold the Power button on iPhone down for 3 seconds:

(b) Now simultaneously hold the Home button and keep the two buttons pressed for 10 seconds:

(c) Now release the Power button while keeping the Home button pressed until Redsn0w detects the device:

Step 6: Your iPhone should reboot now. Please remember to release the Home button.

Step 7: Redsn0w will now start preparing the jailbreak data.

Step 8: You will now be prompted to select the jailbreak options you would like. Make sure Cydia is selected and select ‘Next‘ to continue.

Step 9: You iPhone will be rebooted again and Redsn0w will now begin uploading the new RAM disk and kernel.

Step 10: You will now be notified once the jailbreaking process is complete. Click on the ‘Finish‘ button to exit the application.

Step 11: Your iPhone will reboot once again (which could take approximately 5 minutes). After it has rebooted, your iPhone should be successfully jailbroken. You should find Cydia jailbreak app on your iPhone’s home screen.

If you’re new to the jailbreaking world and wondering what to do after jailbreaking your iPhone, checkout our jailbreak apps category page to find out the apps you can install on your iPhone using the Cydia app. Please note that some of the jailbreak apps and tweaks are still not compatible with iOS 5/iOS 5.0.1 so please be cautious while installing them.

Troubleshooting Tips:

Error 16xx:

If you’re getting error 16xx then it is most likely due to host file entries pointing to Saurik’s server. You can either remove the host file entries or try jailbreaking from another computer.

Error 3194:

You have probably not put the iPhone in DFU mode properly. Try the step by step guide again.

White Cydia Icon:

If you notice the white Cydia icon (which fails to launch) after successfully jailbreaking then follow these steps to fix the issue.

  • Launch Redsn0w again.
  • Click on Extras and then click on Just Boot from the list of options.
  • You will now be prompted to plug your iPhone to the computer and switch it off. Follow the instructions in the correct sequence and click on ‘Next‘ to move to the next screen:
  • You will now need to put your iPhone into the DFU mode. Redsn0w will take you through the necessary steps:
    • Hold the Power button on iPhone down for 3 seconds.
    • Now simultaneously hold the iPhone and keep the two buttons pressed for 10 seconds.
    • Now release the Power button while keeping the Home button pressed until Redsn0w detects the device.
  • Your device will reboot and you will see the Pwnage icon on your iPhone’s screen for few minutes.
  • After your iPhone is successfully rebooted, you will see the regular Cydia icon (brown). You should now be able to launch Cydia without any issue.

Cydia Issues:

It looks like some of the repositories are getting hammered due to the surge in traffic, so keep trying or try after sometime.

“No identifying data was found” Error:

If auto-detection fails and you get the “No identifying data was found” error message when you use Redsn0w then you need to manually select the iOS 5.0.1 firmware file before following the step by step instructions mentioned above. To select the firmware file manually follow these steps:

Update 1:

If you’re having issues launching jailbreak apps install the latest version of Corona iOS 5.0.1 Untether. More details available here.

Update 2:

iPhone Dev team has released Redsn0w 0.9.10b2 to fix the launchCtl issue. We’ve updated the download links with the latest version of Redsn0w.

Update 3:

iPhone Dev team has released Redsn0w 0.9.10b3 to fix the problem with MobileSubstrate based jailbreak apps. We’ve updated the download links with the latest version of Redsn0w.

Update 4:

Corrected the links for Redsn0w. Thanks everyone for pointing it out.

Update 5 (17/01/2012):

iPhone Dev team has released Redsn0w 0.9.10b4 to fix the iBooks issue. We’ve updated the download links with the latest version of Redsn0w.

Update 6 (29/01/2012):

iPhone Dev team has released Redsn0w 0.9.10b5 to fix the iBooks DRM issue. We’ve updated the download links with the latest version of Redsn0w.

Update 7 (15/02/2012):

iPhone Dev team has released Redsn0w 0.9.10b5c to fix some bugs. We’ve updated the download links with the latest version of Redsn0w.

Hope this helped. Please don’t forget to let us know how it goes in the comments and drop us a line if you hit any issues and don’t forget to give a donation to pod2G for all his hard work.

  • Ashbel

    Hi, I have an iphone4 jailbroken on 4.3.3 and i have been trying to update to 5.0.1 and still getting a message that says: The iphone could not be restored. An uknown error ocurred (21).

    Sorry my english guys and thaks for any help you can give 🙂

    • lalo

      someone can help me here please!?!?!?!

    • asdfsd

      I was getting error 21 as well. There was an entry in my hosts file that was redirecting to cydia. Remove this line, reboot the computer and you should be good to go. (an easy way to see if this is your issue is to type in in your browser and see if it takes you to Cydia.)

      • iRockU

        Thanks! I was getting that unknown error 21 also when trying to restore back to factory on my windows 7 laptop. I switched to another PC with windows XP and removed that line because the laptop wasn’t letting me run it in Administrator. Worked like a charm, no problems on my XP.

    • Nomidara

      You can’t upgrade to 5.0.1. You must restore the device ( wipes everything) to 5.0.1 then resync.

      • fahad

        i am getting error http 1.404 not found

  • i0x13h

    i’ve a iPhone 4 thetered… (with may applications, music, video, photos etc)

    can i switch to unthetered? or do i need restore iphone before jb?

    • ian

      Yes you need to restore to re-jailbreak. Of course do a backup beforehand.

      Good luck

      • i0x13h


        i Thought that it would be easy to switch tethered to untethered!

        • iphone 4 user

          well it all depends on if you are already on 5.0.1 if you are go to cydia and search for corona untethered and install package and your done thats what i did lol worked like a charm 🙂 good luck

  • xelon

    Damn.. Error! no successful firmware download after 60000ms!! Giving up…

    • Nick

      i got the same error? any clue on a fix?

      • taz

        if u r on ios5 already then update via fone its hardly 45mb. otherwise download the ipsw of 5.0.1 and update manually via itunes. the itunes downloader is SH*T

  • ian

    Just wanted to say thank you to all involved in the making and release of this wonderful extra xmas present.

    Great work 😉

  • Leo

    How can i do it without upgrade my baseband?

    • leo11jai

      you need to create a custom firmware. use redsn0w 9.10b1 to create one.

  • Tony

    Very easy !! Finally untethered now! Great xmas present 😉

  • mani

    stuck on identifying….any suggestions

    • Odd-Sprout

      I too am stuck on identifying! Any one have suggestions for us? Are we doing something wrong? I’ve always been able to jailbreak prior to this!!

    • t jones

      point the redsnow to the ipsw: ie Extras->Select IPSW.

      worked for me

      • PrashanGune

        I love you!! It just fixed my iPhone from jailbreaking. Thank you so much. But i cant unlock the factory lock in the mobile 🙁 it has 5.1.1

  • Saez

    Get an error when updating to 5.0.1, amy suggestions??

    • xelon

      WHAT error? Not eligible? 1600?

      • lalo


  • indi_dal

    tried to jailbreak to allow use by tmobile sim…. but doesnt work and now I cant use my att sim either any suggestions?

    • iphone 4 user

      what do you mean you tried to unlock after jbing

  • Jerry Berry

    Everytime i try and put it in DFU mode it just boots up again.

    • leo11jai

      you have to connect it to the computer so that the phone can go into dfu mode.

  • GP

    Why does the redsnow app keep unexpectedly quitting?

    • Chelo

      This happens to me as well haven’t been able to complete the jailbreaking process

      • Melvin

        sorry about my typo’s, typing on iphone while at work!!! lol

    • Gil

      make sure you’re going along with the steps as redsn0w is doing them on the screen. If you put it into DFU before running Redsn0w when you go to the steps process it will close out.

    • solferico

      Are you running redwsn0w as Administrator?

  • Nicely Done with no problems >>> anyone who needs help with anything im ready to assit you >>

    • GP

      Why does the redsnow app keep unexpectedly quitting on my mac during the downloading package process?

      • GP

        Never mind, had to go into DFU mode an alternative way.

        • Jhamu

          Is your problem solved? i am also facing the same on Windows machine.
          please explain if you did it….

          Thanks in Advance.

          • taz

            1. open redsnow
            2. click jailbreak.
            3. do not click next
            4. get the fone in dfu mode manually.

            the installation will start automatically and u wont get the unexpected error then. i tried and it worked. cheers!

      • shahbaz

        Hi, it’s finished the jailbreak and it’s supposed to take like 5 minutes for the phone to reboot but mines staying at the apple logo screen and it’s been more than 15 minutes!!! HELLLLLP!!!

        • ray

          same problem! please helppppp!

    • Dave

      Hey, thanks in advance~
      I’ve got an Ipod touch 4G, the jailbreak process is all fine but I cant add any sources or even use the search function on Cydia

      • Dave

        Problem solved, have to change international setting to US

      • David

        I can’t find SBSettings for example, any idea why? I’ve added the repos

    • Greg

      Please help 🙂
      I was tethered on iPhone4 w/ 5.0…. then upgraded to 5.0.1 today. After upgrading and downloading redsn0w on my mac, I go through the process and it reboots the phone but hangs on the Identifying screen. The phone just restarts without Cydia installed. Any ideas? Thanks in advance!!!!!

      • Greg

        Tried 2 different computers 🙁 iPhone reboots and Redsn0w screen sticks on “Please wait while your build is being identified. Waiting for reboot.” The phone reboots without Cydia. Never had these problems before…

        • Fyta

          I think I had this problem last time. It ended up being an issue of not holding the buttons long enough. Even when redsnow

          • Fyta

            … starts doing stuff and stops showing the countdown, keep counting and holding.

        • Anonymous :)

          Had the same problem!!!! took me too long to figure out the solution…..

          The solution is to download firmware 5.0.1 for your phone and then on redsnow go to extras and then click select ipsw and select the 5.0.1 firmware you downloaded 🙂

          Then go to jailbreak and do the rest!!!

    • Vikas

      I used ipsw instead of custom ipsw.
      My baseband got updated to 5.16.05
      Can I still unlock or is my iPhone bricked?

  • iphone 4 user

    any one tried ibooks yet i used corona by chronic dev team and my ibooks don’t work again anyone know if its the same in redsn0w

    • ian

      I JB through Redsn0w and ibooks is fine for me

  • Martin

    Did everything correctly, double checked that I had selected ‘install cydia’, nevertheless Cydia is not installed on my jailbreaked phone. What to do?

    • iphone 4 user

      are you already on 5.0.1 if so i would try using the cydia app use search for corona and you should see the untethered patch worked perfect for me good luck

  • Drm

    Man congrats to alllllll who made this u r the best

  • Jonathan

    Does this work on firmware 04,11,08????please!!!

    • xelon

      04.11.08 is the baseband, not the firmware..

      • Jonathan

        Does it work on that baseband?:)

        • iphone 4 user

          the baseband don’t matter to jbing only if you want to unlock and your baseband can’t be unlocked so along as your on 5.0.1 then your all good to go hope this helped

          • Jonathan

            Thanks a lot! So I’m gonna need to wait for a unlock for baseband 04,11,08 to come out??

  • iphone 4 user

    Jonathan yea mate you are gonna have to wait because not even the gevey sim will work with that baseband. lets hope muscle nerd can work his magic soon lol 🙂

    • Jonathan

      Lol thanks a lot bro

      • iphone 4 user

        no probs man

        • anders

          Hi there,
          I’ve successfully JB:d my 3Gs phone, ios 5.01, yet ultrasn0w won’t work. I can download it from Cydia and run the app but my new sim card can’t find a net work. It say “No Service” after a minute of “Searching”. My firmware (06.15.00) should be compatible. Any ideas?

          • tiago

            same prob here anders, firmware 05.16.05

  • aialek

    Am I the only one who thinks, it would be awesome if you could get the old-school-cell-phone keyboard (the one with only the 0-9 plus # and * buttons) on your iphone, instead of the entire alphabet? .. some android might have it..?

    if you know, that this form of keyboard is already available, then please help me..

    thank you

    • ian

      I’ve also been searching for the keyboard you mention.

      I hope someone can point us in the right direction 🙂

      • aialek

        glad to hear i’m not the only one… it would just seem like such an obvious tweak, so I can’t understand it’s not already available

  • asa

    will this work with ios5.0?

    • iphone 4 user

      no sorry mate has to be 5.0.1

  • ash

    already donate a little amount of money!!! it would be more if i been capable to jailbreak my iPad2 to.. but anyways thank you all make this possible!!! 🙂

  • Coolwave

    Cydia icon is white after i used Redsn0w can anyone help me out

    • tK


    • Olaf

      Try rejailbreaking but uncheck the Cydia tab in redsnow this time when it gives you an options list. Hope that helps.

  • Melvin

    for those of u having redsnow unespectedly crashing…..wat u need to do is create a custom ipsw with redsnow….make sure u backup ur iphone on itunes, then in itunes restore with a ipsw that was made with redsnow it should look something like this “NO_BB_iPhone3,1_5.0.1_9A405_Restore.ipsw” after that u can jailbreak with redsnow……worked just great for me good luck……

  • Vince87

    Anyone having issues with iFile? I’m using it a lot and many appear to be having issues with it after JB with Redsn0w I’m still on 4.3.5 on my i4 and wondering if I should wait for beta 2 or the final release…

  • Anuj Dhingra

    Hey thank you so much, was following pod2g on twitter from so long. Worked like a charm for me. Preserved my baseband so that i can use it with gevey sim. 🙂 worked fine. Thank you so much 🙂 best new year gift for me. From india, Anuj

  • Tim

    If I’m on a Verizon iPhone would I have to worry about my baseband

    • Fonzie

      I’m curious about this too! Still on 4.2.8 on iOS4. Guessing if I have no desire to unlock it shouldn’t matter now? If not, Do I just upgrade to 5.0.1, then upgrade the baseband and start the JB process?


      • Fonzie

        Just in case anyone else is curious, I downloaded the 5.0.1 firmware then upgraded using the restore feature in iTunes. Sync’d everything, then followed the JB instructions. All went perfect. Baseband is upgraded to 4.2.10 now, but since I don’t need an unlock, this doesn’t matter. Thanks for all the effort pod2G!!!

  • Finally!

  • i like sticking my finger up to apple

  • Razz

    I was able to get it running but it sticks at the spinning wheel whenever I reboot. I see I still have semi tether on the phone yet it says it is not on. How do I remove semi tether since it isn’t in my cydia anymore since reinstalling cydia. Or how can I fix the spinning wheel at reboot?

  • Clinton

    Doesnt work for me. I have jailbroke many times before. Nothing is new. For some reason my phone will not enter DFU mode (starts exploiting and never stops, but phone instead boots up normally)

    Any suggestions?

    • anon

      start over. I had this problem. I think it has something to do with not being in DFU mode. It finally got past the exploiting part on my 3rd try.

  • BRian K

    No good here. Trying to go from JB on 4.33 3.10.01 get error 21, tried custom BB ipsw still no. Oh well.

    • iGod

      need to update to 5.0.1 stock, if u have a baseband u need to keep then create a cfw 5.0.1 without bb update, put phone into dfu using redsnow then retry updating, if that fails u need to remove itunes hosts from ur hosts file.

  • Leeree

    I dont see anywhere if u need original sim card after installation ??? Does it fix it or not (hacktivate)

  • will this also unlock baseband 05.16.05?

  • Steven

    After I enter the DFU mode then redsnow runs through its things then it stops at “waiting for reboot” after the phone reboots and doesnt do anything after that….
    any ideas???

  • Bogs

    Is anybody having issues with my3g stuck on expired trial version even if the cydia app was paid for after the jailbreak?

  • Thomas

    I can get Cydia installed, but whenever i install a package that requires rebooting my phone will not reboot. it is stuck on the rebooting screen. i have restored it and tried booting tethered and it still doesn’t work. Seems like there are still some bugs

    nvm. I kept refreshing (like f’n elebenty times) and it finally worked. I guess their servers are overloaded.

    • Jonas

      Just restart the jailbreak, or just press home?

      • repose

        Sorry I didn’t see this earlier. I meant I just kept refreshing the changes section in Cydia

  • Randomicious

    For the iBooks configuration error, I did some searching and found a fix for the iOS 4 jailbreak, which led me to the iOS 5 fix. Add to your sources and then search for “iBooks fix 2”. It’ll say it’s for iOS 5. Installed and worked like a charm, hope this helps 😀

  • lamby

    Jailbroke the 3gs with ease, a big thank you,, but when ive come to install winterboard i’m getting this warning
    ‘Note:the requested modificatations cannot be applied due to required dependencies or conflicts that cannot be automatically found or fixed’
    Any ideas folks Cheers

  • Pedro Niza


    I already created and sucefully installed the cfw 5.0.1

    What should I do right now ?

    tks in advance

  • Pedro Niza

  • luke

    after jailbreak process my cdma iphone 4 is stuck in an apple boot loop. any ideas on a fix??

  • I’m sad

    The jailbreak went well. Cydia icon is white but who cares. That can be fixed later. All the repos I add have a error. I file won’t work. Folder enhancer won’t even load right. Why do all the repos show a error code? Why don’t the tweaks load right? Kind of pointless to have cydia or Unteathered jailbreak if none of this is working.


    Ran Redsnow on 1st PC. Manage to jailbreak. No problem.
    Start redsnow in another PC. Redsnow crash with unexpected error. Restore and jalbreak again. Same error. Any help. Both PC on windows XP sp3

  • hikodavid

    I cant download anything from cydia it keeps on giving me an error when i hit install

  • jamesjones

    There’s only one thing you forgot to mention on this JB, ORIGINAL SIM FROM BASEBAND is needed!
    Now I’ve got to recover, because I don’t have a SIM!!!!

  • Sunilkumar

    Caution: you will be able to successfully update to ios 5.0.1 without upgrading your baseband. but please be aware that you will be stuck at activation screen on your iphone if you are on other carrier.
    I upgraded from 4.3.1 (BB 4.10.01) to 5.0.1, and then had to activate using a regular AT&T Card. i was using Gevey Sim Earlier.

  • vwstadt

    I’m on 5.0.1 already, with 5.16.05. Will my baseband get updated any further? Since I can’t unlock 5.16.05 it doesn’t really matter, but I’m still curious.

  • Nutz

    I encountered error while performing the jailbreak and will appreciate any help or advice.

  • Expert

    After 24 of using i notice these problems, maybe someone know how to solve it:
    1. iBooks – after installing it works, but after download iOS 5 manual app crash forever showing same error “reinstall or smth” but it wont help. Fixed only when downloaded ibook fix for ios5 from cydia, but it’s not only fix, but with app, so i uninstall original from iStore and using that from cydia without problem.

    2. Find my iPhone wont work. Everything is enabled and working when we are talking about iCloud, connected, new email is created too, also i try to do and i can see my iPhone in “find my iphone” devices list, but it says it’s offline, unavailable and wont work, iPhone not receive any sound or messages from there too. Previous with iOS 4.3.1 everything works fine even in iCloud when i login as i remember and with mobile me of course…
    BTW: location service on iphone works fine, tried to catch signal in outdoor too, everything is fine with it… Phone is always on WiFi and 3G too :>

    3. Before updating to iOS5 i make bakcup, but… i cant to restore backup via iTUNES 😉 it’s not so bad, i will have clean iOS5 and rebuilt my programs and files again, but strange… why this problem exist because Apple is guaranteed everything must be fine with it.

    BTW: now iP4 is faster, smoother, smarter and i love it… 😉

  • I’m sad

    I keep getting a posix error in cydia.

  • Rick Burke

    I’ve just upgraded my 3GS (new bootrom) to IOS 5.0.1. I’m going through the described steps but Redsn0w is saying ‘Couldn’t download required ISPW….errror with SHSH blobs’ Does Redsn0w need to download a custom ISPW?

    • Rick Burke

      Top tip. Don’t attempt to do the jailbreak whilst at work where the firewall will almost certainly prevent Redsn0w doing its stuff! D’oh.

      JB @ home in 5 minutes, no problem……

  • Mussie

    Ive jailbroken successfully -but i cant install any cydia apps- winterboard, activator, sbsettings etc… basically every reason to JB isnt working

  • Dan Bradley

    Everything finally started to work late last night. All of my Cydia apps re-appeared. I am having a few technical issues with icons disappearing within folders, but I will figure that out soon. Other than that, it looks great! Oh and lock info is a bit weird, when I receive a text message through “imessage” it appears as that persons email add. instead of their contact card.

    Great work guys!

    Many thanks for replies..

  • Alan

    I have just jailbreaked my iphone 3gs (5.13.4 / 5.0.1). Cydia>Manage>Source>Edit>add “”, and no “ultrasn0w..” show up. I couldn’t unlock it, do you guys know any how?

  • craigx

    thank you so much for this wonderful jailbreak! works 100% with iphone 3gs bb 6.15 (from ios 4.1)

  • ifonix

    thanx dev team for the good and hard work!!
    unfortunately imac G4 or G5 with IBM (not intel) processor can’t open resn0w_mac0.9.10b3.
    you can download the file. you can unzip it..but kick on the redsn0w logo (shortcut)
    give right away..”you can’t open the application “redsn0w” because it is not supported on this architecture.”
    so as a veteran jailbreaker on G4 who jailbroken sins iphone 2 for my self and others..
    what a shame that i have to find different computers to jailbeak my iphone 4… :-/ sh*t

    but once again, thanx dev team and the rest of the jailbreak developers.
    keep doing this secured work for the benefit of all jailbeakers.
    happy new year 🙂

  • Hi

    Awesome post. It worked like a charm. I successfully updated my iPhone 3GS to iOS 5.0.1 and jail broke it. Only concern I have is notification. Only messages and calls I get notification. I have other apps like Facebook, Cricinfo, Wordfeud for which I don’t get notification even after I set these apps in my notification list in Settings. Is there anyway I can get these notifications too..? I used redsn0w 0.9.10b1.

    In past, I had already jailbroken my iphone 4 4.3.5 Tethered. But unfortunately, because of my bad, i forgot to charge the battery so It was run out of battery. I tried to go back to factory restore then I got my iphone 4 5.0.1.
    Now, I did jailbreak Untethered 5.0.1, but I’m getting problem with my Cydia. “add source” + “search”(usually used to search any program that we want to install, and its located on right bottom side) cannot be accessed, when I try to add source, it always goes back to main menu and also “search” does. How to solve this problem? Please help me. Thanks.
