I need your help. I'm going to reinstall windows and was wondering what will happen with the contacts stored on my iPhone when I sync to the newly installed system.
Or what file(s) should I backup now before formating and reinstalling windows.

I have alot of contacts and it's a huge shame loosing em all and entering them all over again.

Any help would be appreciated!
Thank in advance
