sorry for asking what I think is a simple question,but having only had my 7650 for a week,and after having a play with the phone,I now find I have a message in my out box,which is showing an outbox icon all the time which I would like to get rid of.accessing the out box only gives me the option of creating a new message,message details,or exit!please,how do I delete this infuriating icon and message?
