Back-up contacts in galaxy s. Help needed please!

view story

http://androidforums.com – My Samsung galaxy s (froyo) LCD screen cracked. It doesn't show anything after i turn on the phone now. I tried to back-up my data using Samsung Kies and i was successful in copying photos and videos but not the contacts. The program stopped and failed to load my contacts. I am wondering if there is a file in the phone that stores all contact information, which i can copy and paste into my desktop (i can still access the phone using a USB cable connected to my desktop). Any help will be much appreciated, thanks! (General)
