Q: iPhone 5 contacts back up to PC

Hello TerryandAndrea,

I understand that you would like to back up your contacts that is on your iPhone. That is something that I can help you out with. 

The best way is to make a backup in iTunes or iCloud. This will back up everything or a selection of your choosing. This is helpful if you need to move to a new iPhone as it will put your content back on for you. 

Another option is to sync the data. With your iPhone plugged in to your computer, open up iTunes. Locate your iPhone and look in the Info tab to see your syncing options for your contacts.

Take at look at the first two articles for transferring content as well as syncing content to and from your iPhone.
