The easiest way is to go within your Contacts app, under settings there should be manage contacts. Under that heading you will see Import/Export contacts. That will give you the option to export it to your sdcard or to an internal storage. Either way the file provided can then be transferred over to your computer and opened using Outlook or imported into your Gmail or other online/desktop email applications or moved and imported into a new device. I think the common file created is in vCard format.
