This will backup your contacts (and other data) to your iCloud account.


iTunes Backup:

Connect your iPhone to your computer and open iTunes.

Click on the iPhone icon in the top left corner.

Select "This computer" and click "Back Up Now".

This will backup your contacts (and other data) to your computer.


Export contacts to VCF file:
