unable to retrieve CELL-id and LAC on nokia S60 (tried in E50)

Question

I have been trying to get celllid,lac,mcc and mnc. While mcc and mnc can be found,cell-id and lac still are null.Here's the code (and it is known to work according to number of threads going on but I still can't get it to work)

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;


public class LocInfo extends MIDlet {
private Form form;
private Display display;
public void startApp() {
form = new Form("Location...");
String cellid = getCellId();
String getLAC = getLAC();
String getMCC = getMCC();
 String getMNC = getMNC();
form.append(cellid);
form.append("<-this is cell-id");
form.append(getLAC);
 form.append("<-this is LAC");
form.append(getMCC);
form.append("<-this is MCC");
form.append(getMNC);
form.append("<-this is MNC");
display = Display.getDisplay(this);
display.setCurrent(form);
}
public void pauseApp() {
}
public void destroyApp(boolean unconditional) {
}

public static String getCellId(){
String out = "";
try{

}

I have taken code from here (I want it to run on nokia e50 as of now and hence used com.nokia.mid.cellid (in fact i have tried all other options mentioned on this link as well)) Cellid and lac both returns null while mcc and mnc are returned correctly.

I confirm Cell ID can't be received from E50. But I have written kind of multiplatform solution and I am going to check this on wide range of devices (>1000 devices in our production enviroment). I'd got the prototype from same link but to be honest - person who wrote it doesn't give a shit to details.

I very doubt my code will work on at least half of the devices but we will see it soon anyway.

    package Device;

import dct.CellData;

public class DeviceInfo {

    static private DeviceInfo instance;

    private int platformID;

    static public DeviceInfo instance(int platformID) {
        if (instance == null || instance.platformID != platformID)
            instance = new DeviceInfo(platformID);
        return instance;
    }

    private DeviceInfo(int platformID) {
        this.platformID = platformID;
    }

    private String readProperty(String propertyName) {
        String val = System.getProperty(propertyName);
        return (val == null || val.length() == 0 || val.equals("null")) ? "" : val;
    }

    /**

            out = readProperty("CellID");
            if (out.length() > 0) return out;

            out = readProperty("phone.cid");
            if (out.length() > 0) return out;

so have you been able to get the code to work? I am interested because I am thinking of implementing it within LWUIT. thanks for your response, in advance. — Daydah, Apr 12 '12 at 08:57

Which you site mentioned in that have you read this line

But get Cellid is still limited by mobile phone platform, Sign-certificate and Operator:

Nokia s40 3rd Fp1 edition, requers operator or manufactureer signing S60 3rd edition, FP2(released 2008 and newer, does not work on e.g. N95),no singing required.

I didn't get what is that supposed to mean but nokia developer library -> http://library.developer.nokia.com/index.jsp?topic=/Java_Developers_Library/GUID-A1F90B63-5F14-4829-BCA1-A23B925CF670.html mentions "Note: From Series 40 5th Edition FP1 to Series 40 6th Edition FP1, this property is available only in the manufacturer and operator domains. From Java Runtime 1.0.0 for Series 40 onwards, this property is available in all domains" . So that If i am not wrong means that it is available without signing in E50 which is a symbian Series 60 phone... – lalchetian Jun 23 '11 at 12:18
and I just tried it on E63 which is a S60 3rd edition fp1 phone and surprisingly,It gives Cell-id but no mcc,mnc and lac.E50 on other hand returned mcc and mnc but no Cellid and LAC. – lalchetian Jun 23 '11 at 13:04

I just got a Nokia device S60 whit Symbian release 5 here at work, and I'm trying to get the cell phone location based on the cell id, not the gps. So, for that, I use http://www.opencellid.org/, this page retrieves me the position, but it is not exactly such as the gps'. But, for doing that I need the mnc, the mcc, the cellid, and the lac, and for my surprise, this device is not giving me the lac, mnc and mcc, such lalchetian said. We have a serious problem, here. It might be that these properties are only available in some devices only.

unable to retrieve CELL-id and LAC on nokia S60 (tried in E50)
