    i have just checked with voafone asking them to check the imei number and its not coming up as stolen or contract with no issues but the phone will only work with either a t-mobile,3 or orange sim card does this mean it was unlocked improperly

    It can't be unlocked improperly,
    When unlocking a Blackberry device it's simple done by a unique unlock code, if the unlock code is accepted then it's unlocked.

    Then the unlocked Blackberry Storm 9520 can work with sim cards from other carriers.
    see if the bands that used by your carrier fit the 9520 frequency bands support for 2G - GSM 850 / 900 / 1800 / 1900
