hey guys,
i have a nokia 5800 and i want to create a new lock code!! but i forgot my old one!! i used to use a lock code long time ago, and i need to change it,, now my phone is open, i mean i can go to settings and change it but i forgot the old one!
i tried to "hard reset" the phone but it didn't work,
so is there a file in the phone that got the code in it or something?

thanks in advance
and sorry for my english!
