Answer 1

Add the following to your onCreate method:

getSupportActionBar().setDisplayHomeAsUpEnabled(true);

and define the following override method in your activity:

@Override
public boolean onOptionsItemSelected(com.actionbarsherlock.view.MenuItem item) {
    switch (item.getItemId()) {
    case android.R.id.home:
        onBackPressed();
        break;
    default:
        return super.onOptionsItemSelected(item);
    }
    return true;
}
