Reverse syncing iPhone contacts.

I've added some contacts to my iPhone that aren't on my computer. I plan to buy a new iPhone but i want to sync my iPhone contacts to my PC so I can sync the contacts to the new one when I get it. Is there any way to reverse sync contacts from the iPhone to my PC? I'm running Vista Ultimate 32-bit by the way.
Please don't tell me how to reverse sync songs and videos, I've seen many guides on those already and none really helped.

Connect your iPhone and click on the iPhone under devices on the left hand side. Under the "Info" pane, the first option listed is Contacts. If you check the box, you can select to sync with Microsoft Outlook and other options. It backs up all of the contacts from your phone and puts them in your contacts in Outlook. It keeps the list up to date everytime you sync. Any changes you make on the phone will be updated in Outlook and vice-versa. If you want to add a contact on your PC quickly, it will be on your phone next sync

In itunes, when connected to iphone, and when you check the contack box,and sync them, itunes will pop out asking whether you wanna merge them. Just try and see.

Import all the music/video files into iTunes that you want to sync with your iPhone. Then just plug your iPhone into the computer and follow instructions that pop up if there are any. If should automatically sync once its plugged in, but if not click the Sync button

Can someone please help with syncing my iPhone 3G?
Everytime I plug in to try and sync, iTunes will get stuck on syncing calendars, even before I click to sync everything else. What should I do?
This happens on mine. Delete off what is on ur calendars on ur iphone and delete any reminders in windows calendars as well. Try again! If not just be patient leave your pc on overnight and if it still does not work contact apple!
