    Welcome to Crackberry.

    Let's first check that the code really was accepted.

    Go to Options, Advanced Options, SIM Card. Check that it says SIM Card: Security disabled at the top of the screen. If it does, the unlock worked.

    Now make sure that the SIM card is correctly inserted and well seated. You need to take the battery out to do this.

    Please check that the radio is switched on. Do this by finding the aerial-like icon, clicking it and then checking the Mobile Network checkbox.

    This should now result in the phone picking up an O2 signal.

    If none of this works, please come back here and we will dig a bit deeper.

    Then the unlock did NOT work. Have a look at this post http://forums.crackberry.com/f157/ho...ckberry-26109/ to see if it will help.

    Here is what I did to unlock my old 8310. It should be the same for the 8900.

    Full unlock instructions are shown below.

    Yu need to buy and unlock code from a vendor. The unlock code is unique to each BlackBerry and the vendor will require the IMEI code and the device PIN. Bith these cane be found by going to Options, Status. Both these numbers are also unique to each BlackBerry.

    A Curve sample unlock code: 11223344

    1. Scroll to the Airplane Icon (Turn Wireless Off.)
    2. Press Select.

    4. Release the ALT key, it should then display a list

    MEPE is the same key as MEP2. You just need to press the Alt-key to get a 2.

    You should type MEP2 but if that fails, try MEPE.
