    Default how to unlock and jailbreak Iphone 3GS, version:3.1.2 (7D11), Modem firmware:05.11.07


    I am new to this forum and new iphone user. I have purchased the 16GB 3GS
    version:3.1.2 (7D11), Modem firmware:05.11.07 iphone from US on 20th Nov 2009. It was never jailbroken or unlock earlier. I want to use this phone in India with Vodafone as service provider.

    Plz let me know the procedure to jailbreak and unlock the phone. I am scared if any thing goes wrong during the steps then how to restore the original setting.

    1. Procedure to unlock the iphone so that i can use it with Vodafone in India.
    2. Will all the applications work after unlocking the iphone.
    3. What are the side effects of unlocking it.
    4. Any precautions after unlocking the iphone.
    5. Can i do it offline. ( As I am in India so no AT&T network)
    6. is WIFI must during unlocking and jailbreaking process.
    7. Can i restore the original settings at any moment if any thing goes wrong during the jailbreaking and unlocking.

    Thanks in advance.

    2. App Store Applications?

    3. There have been many problems people have had with jailbreaking/unlocking there iPhone but a restore [as new] will most likely fix it.

    4. Your iPhone 3Gs MIGHT have a tethered jailbreak so you will NOT be able to reboot, If you do you will have to rerun blackra1n.

    5. Your PC will have to be online to download blackra1n

    6. No

    7. Yes!

    Do a search for "tethered jailbreak"!

    If this is a new 3G[s], then it can still be jailbroken or unlocked, but you just can't ever let the battery die, or reboot the iPhone when the iPhone is not near a computer.


    The phone is new. Apple updated the hardware on newer models. Ultimately, when you get the "Connect to iTunes" message, DO NOT RESTORE.

    Connect the iPhone to the computer, spend 30 seconds, run Blackra1n RC3/4, RE-jailbreak, and that's it.

    It takes less than a minute.

    ALSO, being that this is a new iPhone 3G[s], that requires a tethered jailbreak, I also suggest getting a battery case.

    A good one is "Case-Mate Fuel" (google it) but it's ugly as sin. It will however, act as a case AND a charger. Or you could go to BestBuy an pick up a "InCase PowerSlider" case.

    That, and a car charger. That way the iPhone never goes off. If you have a laptop, that's ideal/superb.


    Don't download any firmwares from any sites. There's no need to even use PwnageTool right now either. Connect your 3G[s] to iTunes. (Hopefully, you're running the newest version of iTunes) When it asks you if you want to update your iPhone, SAY YES. This will erase any an all jailbreak and unlocks previously there. DON'T PANIC.

    Download and install the official firmware, 3.1.2 from iTunes.

    Go to blackra1n.com and download blackra1n.

    Now, after you restore from iTunes, when everything is about 98% done, it will ask you to insert the SIM card that came with your phone from AT&T. If you have AT&T, great. If you don't, a/k/a T-Mobile, INSERT THAT SIM CARD, and then follow these instructions.

    Open up blackra1n on your PC, and then click "Make it rain" and jailbreak your phone. This will also 'hacktivate' your phone with your alternate SIM card. (Note: follow directions at the end of this post to fix Push Notifications, YouTube and Wi•Fi for hacktivated iPhones)

    YOU MAY NEED TO ATTEMPT THIS MULTIPLE TIMES FOR IT TO WORK CORRECTLY. Sometimes there are minor errors. Let it do it's thing. It is okay and even somewhat expected.

    Once blackra1n.app is installed to your springboard (a/k/a iPhone home screen), choose to install "sn0w"( a/k/a blacksn0w) from your iPhone. Once again, make sure it that you connect to Wi•Fi first. It will be the only way you can install Cydia/Rock if you're not on AT&T.

    1) Open up the "blackra1n.app" on your iPhone.
    2) Tap on "sn0w" until a green check mark appears next to it.
    3) Tap "install".
    4) Watch for the splash screen telling you that it was successful.
    5) Turn your iPhone off.
    6) Insert your SIM card.
    7) Turn the iPhone back on.

    After installing sn0w, install Cydia.

    1) Open up the "blackra1n.app" on your iPhone.
    2) Tap on "Cydia" until a green check mark appears next to it.
    3) Tap "install".

    Cydia will ask you questions, and to update. Select "Graphical User", and "Update All". Let it restart and reboot. Once it does it's thing...

    If you have data or MMS problems with ANY carrier, you may want to google or wikipedia "iPhone APN Settings" to find a way to fix those issues. However, if the plan for the cell carrier SIM card you've inserted does not include data, then your Internet/e-Mail/maps/gps etc won't work. You will have to add data/MMS to that SIM cards plan for them to officially work.

    Voilà. You're updated, jailbroken, and unlocked on the newest OS.

    For some, the new blackra1n HACKTIVATED jailbreak was causing problems with Wi-Fi, YouTube, and Push Notifications. Here is a quick guide on how to fix these problems.

    1. Go to Settings>General>Reset>Reset Network Settings, then click "OK"
    2. Reboot your iPhone, when it comes back on Wi•Fi should be fixed, but next time you reboot you have to do this again.

    YouTube and Push Notifications for "hacktivated" iPhones.

    1. Go to Cydia
    2. Tap Manage at the bottom
    3. Tap Sources
    4. Tap edit in the right hand corner
    5. Tap add.
    6. Type cydia.iphoneil.net
    7. Tap done
    8. Search for "PushFix" and tap on the first result
    9. Install then confirm
    10. Reboot your iPhone.
