    geohotz has discovered the secrets to unlocking 1.1.3 + 1.1.2 out of the box!!! Whats more this doesnt even destroy your seczone!!

    I haven't had a chance to try it out yet but when has gehotz failed us before?

    If any of you are feeling up to it give it a shot. First grab his gunlock.rar MIRROR and his instructions are as follows:

    geohot's 1.1.2 software unlock
    yes, this is what you have all been waiting for

    1. Download these:
    gunlock and the secpack from http://iphonejtag.blogspot.com/ or the blog
    the 4.02.13 fls from http://george.zjlotto.com/index.php/baseband/ MIRROR

    2. Downgrade your phone to 1.0.2. See all the great tutorials online to do this.
    Your baseband won't be downgraded, this is normal.
    This will probably work on other versions too, but 1.1.2 doesn't lose wifi on bb access.

    3. Kill CommCenter and run "gunlock secpack ICE04.02.13_G.fls"

    4. Reload CommCenter. For some reason my phone was in brick mode. Use the elite team bricktool to get out.

    5. Enjoy your 1.1.2 OTB unlocked iPhone

    Now who'd have thought it'd be this easy

    This release is no thanks to elite/dev
    I wish they would share like the old days.
    I don't believe everyone in the team is like this, but come on guys.

      Yes! I am 100% sure about this since I've got a fully functional, soft-unlocked 1.1.2 OTB lying in front of me. Here is a short and simple tutorial:

      1. Open Instller on your jailbroken 1.1.2 OTB and install OpenSSH and Term-vt100 (under System)
      2. Connect via WiFi to your iPhone using WinSCP
      3. Copy all the files (gunlock, ICE04.02.13_G.fls and secpac) to /usr/bin
      4. Set permissions of gunlock to 755 in WinSCP
      5. Put iPhone in Airplane mode (IMPORTANT!)
      6. Execute the following commands in Terminal:

      launchctl unload -w /System/Library/LaunchDaemons/com.apple.CommCenter.plist

      gunlock secpack ICE04.02.13_G.fls

      launchctl load -w /System/Library/LaunchDaemons/com.apple.CommCenter.plist

      7. Restart iPhone and throw your ***sim out of the window
      Thanks for the guide.

      Although I have a few questions.

      Does this unlock fix all the problems people have been having with their upgrades to 1.1.3? Or does it just solve the whole unlocking situation.

      Also, why would I want to software unlock my phone if I have a fully working sim-card unlock?

      Here is the translation of Sendowski site that has the file on installer.

      Here are my notes on the Sendowski Method.

      It takes me about 10 mins to unlock a 1.1.2 OTB with it and it works perfectly well on all SIM's I have tried here in Australia.

      Hardest part is actually typing accurately in VT with no back key (please share if there is a secret to getting a backspace/delete?):


      - Jailbroken iPhone 1.1.2 / 1.1.3 OTB
      - WLAN Internet connection
      - Installer (AppTapp)


      1. Set Autolock to NEVER

      2. Installer - “System” - “BSD Subsystem”

      3. Installer - Source - “Edit” - “Add” - “Add Source” - "http://www.sendowski.de/iphone” - “ok”

      4. Installer - Install - “sendowski.de Unlock” - “Gunlock - Files only”

      5. Installer - Install - “System” - “Term-vt100″

      6. **IMPORTANT** Set Airplane mode ON!

      7. Start Term-VT


      cd /usr/bin

      /bin/launchctl unload /System/Library/LaunchDaemons/com.* apple.CommCenter.plist

      ./gunlock secpack ICE04.02.13_G.fls

      /bin/launchctl load /System/Library/LaunchDaemons/com.* apple.CommCenter.plist

      8. All Finished

      Couple of Notes:

      1. After typing the first unload command above, VT gives no feedback and no longer gives any sound feedback as you type...This is perfectly fine

      2. After doing the ./gunlock step, you will get a message saying "Enjoy your Unlocked Phone" but remember, you still must load the CommCenter again.

      3. After typing each command in VT, just hit Return. The first 2 and the last command give no feedback at all (ie, it just gives the cursor prompt) and that's ok.


      The Geohot unlock only unlocks the SIM you still need to hactivate / jailbreak you can stick with 1.1.2 or use the dev teams soft upgrade to 1.1.3

      Dont upgrade to 1.1.3 with iTunes or you will be locked out of your phone & the phone will ask to activate.

      THANKS w9cae !

      (1.1.2 OTB no more stealth sim!)
      where to get 'ICE04.02.13_G.fls' and copy into usr/bin?

      I have a OTB 1.1.1 on o2 iPhone contract, updated via iTunes to 1.1.3. If I use this unlock will I be able to use 1.1.2 firmware with phone capabilities? Or will I still need to get back to 1.1.3?

      Hi, I´m new on the forum, waiting for my 1.1.3 OTB iphone to arrive by late February from the US to my hands.

      I´ve read this forum, and marcelse tried it up on two 1.1.3 OTB and he wasn´t able to unlock it.

      Has someone been successful on 1.1.3 OTB?, if so, can you CONFIRM IT??

      because, there´s lots of post saying about 1.1.2 OTB... but a few about 1.1.3 OTB

      just to clarify, this will allow those with a 4.6 to have an unlocked phone correct?

      It does not allow us to upgrade from a 1.1.2OTB with itunes 1.1.3 stock so that we have current modem firmware?

      I currently have a 1.1.2OTB with the official dev team 1.1.3 jailbreak. I am still on the old firmware. I use a stealth sim with my sim card for phone service. I assume that this will just allow us to use the phone without sim support such as stealth.

      I want to upgrade my modem firmware, one of the posts above said not to do it yet. So stay with the soft update. So my last question is do I need to downgrade back to 1.1.2 jailbreak, or can I do this from the soft update 1.1.3??

      Thanks for the help

      Use a better method, all you need is your beloved 1.1.2 OTB or 1.1.3 OTB or any 1.1.2 and any 1.1.3 as well as a good WiFi connection to Install Geohots Gunlock Script. No need to connect to PC or Mac. From Installer, go to Sources, Edit, Add http://sleepers.net/iphonerepo and refresh. Go to Install, choose Recent category, find Geohots Gunlock Script. Install BSD Subsystems and Terminal VT100.

      Go to Settings, set Airplane mode.

      Go to Terminal VT100 if you already in 1.1.2 or 1.1.3.

      Type the following (only 2 lines, each end with return or enter)

      cd /usr/bin

      Wait for about 2 minutes, enjoy your 1.1.2 or 1.1.3 unlock.

      In case you are in doubt, read More Info before you install Geohots Gunlock Script.

      Mine is iPhone 8GB from week 51, running 1.1.2 OTB, jailbroken and using x-SIM in tandem with Xplor SIM card from Indonesia, need only 2 minutes to run Geohots Gunlock Script. Now no more x-SIM to be used. Thanks George and BigBoss that put the script in the repository.

      I am now figuring on how to get into 1.1.3....

      Yes, this has already been done successfully on the new 16g 1.1.3 iPhone...
      Just remember, you need to go through the download & Jailbreak process first (sorry if that seems obvious)

      Use the official 1.1.3 upgrade (Dev team method).
      Once you have your jailbroken 1.1.3 iPhone, go to installer, add the source listed above, and begin the new unlocking process.

      The first thing you want to do, is forget about this whole "Unlock" business, and get started on the downgrade/jailbreak process for the OTB 1.1.3.

      Do some searching for 1.1.3 OTB jailbreak.
      You will find everything you need to downgrade your 1.1.3 firmware, jailbreak it, prep it to be upgraded back to 1.1.2 jailbroken.

      Once you are jailbroken on 1.1.2 firmware, upgrade to the 1.1.3 firmware jailbroken using the 'Official Dev Team" 1.1.3 jailbreak/

      Then you will be ready to try this new soft unlock method

      Is better update an 1.1.2 OTB Jailbreaked to 1.1.3, Jailbreak it and Unlock with this method?

      Any try this???
      The way I understand this new unlocking method, you're probably better off getting yourself to 1.1.3 jailbroken before attempting this unlock method if you intend to upgrade to 1.1.3.

      If he is still using a locked non-jailbroken phone, he DOES need to downgrade so that he may jailbreak the phone, then access installer.app to try the new unlock method
