public class Inbox extends Activity implements OnItemClickListener {

    ListView lViewSMS;
    String thread_id, body;

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

        ListView list = (ListView) findViewById(R.id.lvlistViewSMS);
        List<String> msgList = getSMS();

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, msgList);
        list.setAdapter(adapter);

    }

    public List<String> getSMS() {
        List<String> sms = new ArrayList<String>();
        Uri uriSMSURI = Uri.parse("content://mms-sms/conversations/");
        Cursor cur = getContentResolver().query(uriSMSURI, null, null, null,
                "date");

        while (cur.moveToNext()) {
            String address = cur.getString(cur.getColumnIndex("address"));
            String body = cur.getString(cur.getColumnIndexOrThrow("body"));
            String person = cur.getString(cur.getColumnIndexOrThrow("person"));
            String thread_id = cur.getString(cur
                    .getColumnIndexOrThrow("thread_id"));
            sms.add(address + " " + person + "\n" + body);

        }
        return sms;

    }

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
        // TODO Auto-generated method stub
        Intent myIntent = new Intent(getApplicationContext(),
                Conversation.class);
        startActivity(myIntent);
    }

Looks like you forgot to add the item click listener to the listview.

list.setOnItemClickListener(this);

You will also need to pass the relevent piece of data to the new activity.

You can do something like

    Intent myIntent = new Intent(getApplicationContext(),
            Conversation.class);
    myIntent.putExtra("msg", myMsgData);
    startActivity(myIntent);

Keep in mind myMsgData has to be one of a few supported formats to pass between activities. Check out this post How do I pass data between Activities in Android application?
