  • Unlock The iPhone 4S Without Any Hardware or Software Changes (AT&T iPhone 4S Only)


    A developer by the name of Caleb Daniels seems to have discovered a method that will unlock the AT&T version of the iPhone 4S without any software or hardware tweaking. As of right now, the method is reported to work only with the AT&T version with a CDMA iPhone 4S method in the works (according to Daniels).

    The unlock will assist you in using your iPhone 4S on T-Mobile’s network as long as you have a T-Mobile SIM card (something you’ll need anyway). Some twitter users have confirmed that this method does work so if you’re interested in giving it a shot, feel free to follow the steps below:

    Quick Note #1: Your T-Mobile SIM card needs to be the size of a microSIM

    You will need to make sure your T-Mobile SIM card is equivalent to the size of your microSIM from AT&T. You can do this by cutting your T-Mobile SIM card yourself with something like an exacto-knife, purchasing a SIM card cutter, or obtaining a microSIM through T-Mobile’s website.

    Quick Note #2: You need a T-Mobile data plan in order for this to work

    One of the steps requires you to have access to Edge, this will only work if you have a data plan.

    Unlock the iPhone 4S (AT&T version) Without Hardware or Software Tweaking
    1. Insert the original AT&T SIM card.
    2. Dial 611 and drop the call.
    3. Turn on Airplane Mode.
    4. Take the AT&T SIM card out.
    5. Insert the T-Mobile SIM card.
    6. Make sure Wi-Fi is turned off (to ensure it doesn’t connect automatically later, just hit “Forget this Network")
    7. Turn Airplane Mode off. The iPhone will search for the network and then Apple’s splash screen will appear. The Activation Required will then be displayed on the screen and the Edge network will activate automatically (check for an “E” in the top left corner of the screen)
    8. Wait 20-30 seconds at this point then turn the iPhone off.
    9. Turn the iPhone back on and the same Activation Required screen will then be displayed.
    10. Continue to wait and when you see one signal bar, hit “Use Cellular Connection”
    11. Eject the SIM card and the Activation Required screen will appear for the second time.
    12. Put the SIM card back in and voila! You will be unlocked!

    The method is definitely something different in terms of how the community has been unlocking their iPhones in the past but it has been confirmed to work. If you end up trying it out, share your experience below! Furthermore, feel free to discuss any issues or whether or not the method worked or you!

      Pretty sure I know the answer, but I suppose it wouldn't hurt to ask!
      yea i second that, and if it is a perm then ill get tmobile as well just to unlock it.

      Funny thing is ATT could make a bundle having you pay to unlock your phone. I know I would pay about $50 for a permanent unlock. It would just be nice to know that there worst case scenario in updating would be not being able to downgrade. I don't really even NEED an unlock, but it is nice to know the option is there if/when needed.

      They make a bundle by not unlocking. Anyone traveling with Their locked iPhone is getting raped with charges. Most likely more than $50 for their time spent there. Not to mention that keeping people off other carriers within the the states just makes sure that people actually pay them for use and over use. They are definitely making more by not unlocking.

      Restart the phone after and it should be working.

      This is not the same as a gevey at all. The only thing that is similar is the dial 611 part (gevey is dial 112). The gevey exploit was patched with the 5.0 baseband.

      So if you put the AT&T sim back in, will it revert back like nothing happened? If so, I might give it a try ... I just want to make sure there's no damage done in the process.

      *EDIT - Nvm... I just read all you have to do is reboot. The comments section is only showing the first comment when you click on the story from the home page. The only way I could see the rest of the comments is by going to the thread where this story was originally posted.

      I'm looking at H2O's website and I see the $60 plan but it only comes with 2gb of data?

      I don't believe any of them are truly unlimited past the 5-6GB threshold

      They are unlimited actually. No CAPS etc. I used to have a Jailbroken iPhone 4 with WIFI HOT SPOT/Tethering n use it like CRAZY with no problems at all ;-) !! That's why I said its truly unlimited.

      Well, as far as phone carriers go, on T-Mobile they have a prepaid plan of $50/mo with unlimited talk, text and data. The is up to 4G speeds for the first 100 MB, if you pay $60 instead it's for the first 2GB [None of this matters when using a T-Mobile SIM on an iPhone since you'll get EDGE speeds regardless]. If what koreanmasters99 said is true, that's about the only thing that H2O has over T-Mobile with that $60 plan is the speed, but the data isn't unlimited like T-Mobile. Plus, if I ever have problems with my service, I can just go to a local T-Mobile store and get things fixed. I don't know about H2O as far as that, I've actually never seen a store for customer service.
