Answer 1

another snippet from an applilcation I've written recently:

TelephonyManager telManager;    
telManager = (TelephonyManager) getApplicationContext().getSystemService(Context.TELEPHONY_SERVICE);
int cType = telManager.getNetworkType();
String cTypeString;
switch (cType) {
        case 1: cTypeString = "GPRS"; break;
        case 2: cTypeString = "EDGE"; break;
        case 3: cTypeString = "UMTS"; break;
        case 8: cTypeString = "HSDPA"; break;
        case 9: cTypeString = "HSUPA"; break;
        case 10:cTypeString = "HSPA"; break;
        default:cTypeString = "unknown"; break;
}

Try this stuff,

    void checkConnectionStatus()
      {
       ConnectivityManager connMgr = (ConnectivityManager)
      this.getSystemService(Context.CONNECTIVITY_SERVICE);


      final android.net.NetworkInfo wifi =
      connMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);


      final android.net.NetworkInfo mobile =
      connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);


      if( wifi.isAvailable() ){
      Toast.makeText(this, "Wifi" , Toast.LENGTH_LONG).show();
      }
      else if( mobile.isAvailable() ){
      Toast.makeText(this, "Mobile 3G " , Toast.LENGTH_LONG).show();
      }
      else
      {Toast.makeText(this, "No Network " , Toast.LENGTH_LONG).show();}
      }
}
