    I have an iPhone 5 on Vodafone Ireland..
    I found the phone which had a passcode lock on, I left the phone on in case the owner rang which they never did, but two days later there was not network coverage so I am assuming that they reported it missing and Vodafone blocked it.. If I purchase your unlocking service will it – (1) reset the phone so it no longer has a passcode

    (2) be white listed again so I can use the phone?

  • HELPP!!!

    OKay so i just unlocked my iphone 5. well i think i did but before i did that i had at&t service on it so i went and bought and at&t service sim card. it still didn’t work. it didn’t make no sense and i ran through red pocket which runs through At&t. it kept saying this phone has been blocked from service use, it just kept saying that everytime i try to call. its frustrating on how i went and bought something to unlock the service so i can put something else in but then when i do its keeps saying the same thing. its blocked and go see your phone service to unblock it… any suggestions? answers. i need someone to help me. i know i could go get help but shouldn’t it but unblocked already?

    Official Factory Unlock for 012539008034970 (iPhone 4) locked to O2 UK

    The IMEI you gave us is marked as BLOCKED, usually meaning it’s a lost or stolen handset, but handsets can be blocked for any number of reasons including non-payment of bills, blacklisted, bad ESN and/or contract issues.

    We can easily remove the blacklist from the Apple database, however this requires being sent on a more expensive service which was given to you as a purchase option when you first visited our website. As a goodwill gesture we are willing to send the IMEI on this service if you just pay the difference.
