How to show statuss bar on S40 with LWUIT

import com.sun.lwuit.Display;
import com.sun.lwuit.Form;

protected void startApp() {
Display.init(this);
// whithout the code below i can get status bar. And i think the com.sun.lwuit.Form hide the status bar.
Form f = newForm("testForm");
f.show();
}
I can get the status bar on emulator , but the phone. How can I get the Status bar on phone?

Thanks

Display.getInstance().setForceFullScreen(false);

set true is full screen on emulator, set false is not. But this doesn't work on the s40 phone.
