I have a nokia 6600, and i got given a virus via bluetooth and so it takes up all my money and battery. The virus has embedded itself and I cant find it to delete it. So i need to format my phone. The only problem is I cant remember what my lock code is. Its not the default one as I changed it so my ex couldnt get into it. and the technique of holding the green call buton, + and 3 while starting it up doesnt work for some reason. Can anyone else help?
