We will also give results concerning the primeness and simplicity of crossed products of twisted actions of locally compact groups on $C^*$-algebras.A mistake in the sentance after the proof of Lemma 2 was corrected. We would like to thank Prof. Echterhoff for pointing out the mistake to usOperator AlgebrasDynamical Systems46L05; 46L55text
