Using android TelephonyManager you can get all the information related to network and phone.

Try this code snippet two know the type of the Network on your device:

package com.CheckNetworkType;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;

public class CheckNetworkType extends Activity
{
    private static final String  tag = "CheckNetworkType";

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        TelephonyManager tm =  (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);        
        if(tm.getNetworkType() == TelephonyManager.NETWORK_TYPE_EDGE )
        {
            //  Network type is 2G
            Log.v(tag, "2G or GSM");
        }
        else 
        if(tm.getNetworkType() == TelephonyManager.NETWORK_TYPE_CDMA)
        {
            // Network type is 2G
            Log.v(tag, "2G or CDMA");
        }
        else
        if(tm.getNetworkType() == TelephonyManager.NETWORK_TYPE_UMTS)
        {
            // Network type is 3G
            Log.v(tag, "3G Network available.");
