I called up nokia and asked them how to set my device to factory settings, then he said go to the applications tab>Settings> Control Panel> Then click the button with the one big line and three smaller ones>Tools>Clear device. He said just click ok

Then when it started up, it asked for where i live and the time.

It looked the how i first bought it.

Now i'm really scared that i lost the origional files that the device came with, is it possible for my to update the OS and i will get them back?

What is the latest OS?
I have version 1.2007.42-19, is that the latest?
