    If you are trying to get the cell ID by:

    String cellId = System.getProperty("Cell-ID");
    this will not work on Series 40 devices, even when signed.

    You can get information about signing in the Forum Nokia wiki. There is a lot of information in there.

    Refer to FN wiki : http://wiki.forum.nokia.com/index.ph..._ID_in_Java_ME

    This code snippet demonstrates how to get the mobile cell ID by using Nokia-proprietary system properties in Series 40 and S60 devices. Note that a different system property is used to get the cell ID in Series 40 and S60 devices:

    Series 40 3rd Edition, FP1 (or newer): System.getProperty("Cell-ID")
    S60 3rd Edition, FP2 (or newer): System.getProperty("com.nokia.mid.cellid")

    Note: In Series 40 devices the MIDlet needs to be signed to a manufacturer or operator domain; otherwise the property will be null. Signing is not needed for S60 devices.

    So you need to get manufacturer certificate from Nokia for S-40 to get this done, dont try with 3rd party signature, Contact Nokia Biz dev team.
