Any advice on transfering iphone contacts to itunes?

[youtuy]

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.
Now I'm saving money for the new iphone 5, but 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 don't mind if I have to pay for something but it would be the best if there's a free and easy way.Help me please.

Apple has a built in service that allows you to backup important information to the cloud. It's called iCloud.

It can be found under Settings --> iCloud. Turn on contacts, emails, photos, notes, safari to have these services backed up automatically your iCloud account.

Here is more information on how to setup iCloud on your device:

If you have an ipad/mac you can also sync all the information between these devices.

Another option would be to setup a gmail account and add it to your phone as an exchange account and sync the contacts to your gmail.

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.

You may first transfer your iphone 4 contacts to your computer. and that may right there in your “Address Book” on your computer. If “Address Book” is in your dock, the icon is with “@”symbol. If not like that, go to Applications in Finder and do a search for “Address Book”
Next time, do an Address Book export just to have another back-up if you are not automatically backing up using Time Machine, your iDisk, or whatever. If you back up to a file on the same computer, copy it to an external drive.

You can with the help of Outlook on your computer, create a new folder “Group” under contacts ,then Plug in your iphone 4 to sync with Outlook。
In iTunes select this “group”and make sure to select newly created iphone contacts to save in that same “Group” as well.

I suggest you go to apple's support forum for more information about how to transfer iphone contents from iPhone to PC, once you successfully add the items to to your computer you'll be able to add them to your itunes, there's just one simple step's difference.

Check the synchronization first.
