How do you restore a nokia 6680to factory settings??

Just thought I'd add something I came across on the official Nokia support forums. This was posted by a contibutor, not by Nokia staff. I haven't used it. So use at your own risk. Turn phone off. Holding the the Green, the 3, the* buttons pressed, press the Power button. Personally without more confirmation I wouldn't use it unless the phone was really knackerd and paying to have someone look at it was uneconomical. I think it applies to series 4 phones.
