Below is my code:

public final String getQueryString(){
				// Retrieves the cell id  
				String cellID = Integer.toString(GPRSInfo.getCellInfo().getCellId());  
				// Retrieves the Location Area Code.  
				String lac = Integer.toString(GPRSInfo.getCellInfo().getLAC());  
				// Retrieves the mobile country code.  
				String mcc = Integer.toHexString(RadioInfo.getMCC(RadioInfo  
				                .getCurrentNetworkIndex()));  
				// Retrieves the Location network Code.  
				String mnc = Integer.toHexString(RadioInfo.getMNC(RadioInfo  
				                .getCurrentNetworkIndex()));				
				String queryStr="http://www.opencellid.org/cell/get?key="+myapikey+"&mcc="+mcc+"&mnc="+mnc+"&cellid="+cellID+"&lac="+lac+"&fmt=txt";
				return queryStr;			
	}
	
	public void httpGetRequest(){
		HttpConnection conn = null;		
        InputStream in = null;
        StringBuffer buff = new StringBuffer();
        String result = "";     
        try {
        	conn=(HttpConnection) Connector.open(getQueryString());        	
                in = conn.openInputStream();               
                buff.append(IOUtilities.streamToBytes(in));
                result = buff.toString();
                System.out.println(result);              
        } catch (Exception ex) {
            System.out.println("====Exception: "+ex.getMessage());
        } finally {
            try {
                if (in != null) {
                    in.close();
                }
                conn.close();
            } catch (IOException e) {
            	 System.out.println("====Exception: "+e.getMessage());
            }
        }
	}

But the line highlighted above gives Exception:

Local connection timed out after ~12000

Please help.

I don't think the problem here is related to OPen Cellid.  I think the problem is the http get code.

I would look at the sample httpdemo code to see what a GET should look like. 

And make sure you understand the connection method you are using.  The following network video will help::

This will help too:

Now if you don't want to code connection strings yourself, look at ConnectionFactory.

But the most important thing is to review httpDemo and test this in the Simulator (with BES MDS Simulator running).  Try changing the URL it requests to match the URL your code creates and see what happens too.
