Any advide on transfering iphone contacts to itunes?

So here's the thing, I accidently spilled water on my iphone 4, although it has been fixed, it still get kind of "unstable", sometimes it just suddenly shut itself down.
Since iphone 5 is coming soon, I think I'll wait till then to get a new one.However, I have a pile of important contacts saved on my watered iphone 4 and I'm so afraid that they'll be gone with the damaged phone right before I could get a new one. But if I can copy these contacts to itunes, then next time I'll be able to transfer them to the new iphone,right? Or just copy to computer? Any difference?
Anyway, I just want the contacts to be backuped, any good idea? I use Dell PC with Win 7 system.I don't mind if I have to pay for a tool but it would be the best if there's a free and easy way.Help me please!!

yes its possible in both ways iphone to itunes...you can transfer them

Or even just type in your question into google and get an instant answer.

Or just waste a couple of days posting on a forum to see what kind of spam it attracts.

Some good will hunting

1. Open iTunes and plug in your iphone
2. Under the “info” tab you will see a field that “Sync Contacts with :” and give you a choice of which program you want to save your contacts to .By default, it is Windows Address Book.
3. Check the “Sync Contacts With:”box and choose windows Address Book
4. In the lower-right corner click the sync button and all of your contacts will be immediately saved to Windows Address Book

Next time when you want to sync these contacts to your new iphone, you just add them to itunes library, and I belive you know how to do the rest.
