no tab selected by default

code is given below, problem is i am not able to remove "Main" tab from the code, as it just closes the application, and that happens because once main tab is removed it selects "call" tab default activity... buh i want to have main view as main activity and call or email or web tab only work when a user click on them

Java code

package com.NVT.android;

import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.widget.TabHost;

public class MainTabActivity extends TabActivity{

        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.tab_activity_layout);

            Resources res = getResources(); // Resource object to get Drawables
            TabHost tabHost = getTabHost();  // The activity TabHost
            TabHost.TabSpec spec;  // Resusable TabSpec for each tab
            Intent intent;  // Reusable Intent for each tab

            // Create an Intent to launch an Activity for the tab (to be reused)
            intent = new Intent().setClass(this, Main.class);

            // Initialize a TabSpec for each tab and add it to the TabHost
            spec = tabHost.newTabSpec("main").setIndicator("Main",
                              res.getDrawable(R.drawable.ic_tab_artists_grey))
                          .setContent(intent);
            tabHost.addTab(spec);

            TabHost host=getTabHost();

            host.addTab(host.newTabSpec("one")
                    .setIndicator("Call")
                    .setContent(new Intent(this, CallService.class)));

            host.addTab(host.newTabSpec("two")
                    .setIndicator("Email")
                    .setContent(new Intent(this, EmailService.class)));

            host.addTab(host.newTabSpec("three")
                    .setIndicator("Web")
                    .setContent(new Intent(this, WebService.class)));

        }

    }
