Without GPS or Network Operator we can still use the Location Based Service, via the help of CellId(Cell ID the location of Cell Identities of GSM-networks). Google has one enormous database of cell ids which are linked to a longitude and latitude position, that why Google Map client know where you are even you have no embedded GPS--it is not open. But there are other opened cellid DBs that we can use freely: opencellid , mobiforge.com and http://realtimeblog.free.fr/
Ok, one we can get the cell from phone we can query the location from these cellid DB. In GSM networks, all cells in the world have a globally unique ID made up of four numbers:
cell ID, LAC, MNC, and MCC.

For example, for Motorola:
Using JavaME to obtain Cell Positioning information

    2. 


  2. 

    ….
    


    3. 


  3. 

    String cellid = System.getProperty("CellID");
    


    4. 


  4. 

    String lac = System.getProperty("LocAreaCode");
    


    5. 


  5. 

    String imsi = System.getProperty("IMSI");
    


    6. 


  6. 

    // Example IMSI (O2 UK): 234103530089555
    


    7. 


  7. 

    String mcc = imsi.substring(0,3); // 234 (UK)
    


    8. 


  8. 

    String mnc = imsi.substring(3,5); // 10 (O2)
    


    9. 


  9. 

    String location = mcc + mnc + lac + cellID; // A globally unique ID for a cell
    


    10. 


  10. 

    }
    


    11.

Information from Truly Mobile JavaME Applications: Location, Media Capture, and Connectivity

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

SonyEricsson:
Java platform 7.3 or higher (released around 2006 and newer)
older phone may need firmware update (7.1->7.3)
does not work in SE symbian (ie. UIQ) or windownsmobile(Xperia X1) phone
Information from Terminal-based Mobile Positioning overview

And notice, even you use the right code and sign your application, it is still not possible to query the cellID, because some telecom-operators have limited this service.

The fowllowing J2ME code could help you, J2ME Polish Syntax is used here to make the procedure easier. The functions here is not complete, because some manufactories have not released their J2ME API documents to query the cellID. If you have some information which is not included in the codes please let me and others know, please supplement here, thx!
