Hey guys,


My iPhone 4 has an AT&T simlock. So I searched for an unlock and I found that AT&T unlocks devices older than 2 years. I went to and followed the steps ( Checked the NON-Customer box!!! Entered my IMEI etc. ) . Then i received an Email which said that i need to fax the original receipt. After I did that I received an Email that im able to unlock my iPhone. I followed the steps written in that Email and after restoring there was no "unlock succesful" message. Then i read the Email again and saw that i need to wait 48hrs . After MORE than 48hrs i tried it again and still nothing happened. To activate my iPhone i put the original SIM into it and then it worked. If I put another SIM in it says that this SIM is not supported. Then I repeated the unlock request (sent a new one) and waited again. Nothing happened. Then I waited almost 1 and a half year and some days ago I sent another request and waited. Again my NON-official SIM still didn't work. The only thing I could imagine is the reason that I have a SIM-Pin. But after restore it just says something like: "Please unlock SIM and connect again." So I think it doesn't matter. To activate my iPhone i again used my official SIM and now i still cant use my iPhone as an iPhone. You know what could be responsible for that?


I really need the unlock. Thank you for any offered help!



EDIT #1 : I looked it up on the Internet and I didn't find anyhting!

    As you might have noticed I already received an Email that im eligible to unlock. Unlock Stauts shows the same text as the Email


    EDIT #1: Is it maybe because the iPhone WAS jailbroken some time ago?

    That's your problem.


    You can not get help here per the terms of service.

    That's what the jailbreakers say.  It's obviously not true.


    You need to look elsewhere for help.

    But if i restore the normal way it says that the jailbreak will be removed!?


    Never a guaranteed fix or reversal, as apparently evidenced by your own personal experience.

    The jailbreak is NOT the reason and that unlock method is for std dumb and some android phones.

    It does NOT work with an iPhone as the "lock" is in firmware and on the APPLE iTunes server.


    The correct method is contact your network supplier (ATT) customer service.


    Request the unlock and pay any fees requested (Depending on how long you are in contract they may demand EOL payments).


    Your network supplier then contacts Apple to request the White listing (Unlocking) of your phone on the iTunes servers.


    Apple do this -It takes anything from 3 days to several weeks to complete.


    On completion Apple confirms this back to your Network supplier (NOT YOU)


    Your network supplier contacts you via email or SMS inviting you to connect your iPhone with your computer via the supplied USB cable and launch iTunes and follow on screen prompts through to the "Congratulations your iPhone is now unlocked" screen.


    All these steps need to be carried out with the ORIGINAL SIM and by REGISTERED account holder used when setting up the phone.


    Once the Congats...... screen has been reached you can swap out the REGISTERED SIM and replace with a compatable SIM on another network.




    Only the original SIM and Account holder can initiate an unlock- If you bought the phone used/second hand you CAN NOT UNLOCK through official routes


    Once unlocked use of a Mobile Virtual Network SIM may result in difficulties sending SMS messages.

    You may have to go into Setting /Network/Cellular/Cellular Data Network and enter the correct settings manually.


    Further caveat Cellular Data Network menu is SIM card dependant if its not supported you CAN NOT change the settings manually then you may need to contact the SIM card company - They can send a setup SMS if they support this process.

    The thing some providers  seem to leave out in the instructions is that you have to completely erase your phone, then connect it to iTunes to complete the unlock.


    After the unlock, then you can restore all of your data. (not before)


    But like some are saying, the mention of a jailbreak means that your support here will be limited.
