Deleting all Contacts from iPhone using Sync

I was trying to delete all my contacts on my iPhone and replace it with the contacts on my Outlook. There was no success and later I finally found a way to do it.

Click on your Devices and select your iPhone or iPod Touch and then select the Info Tab. Ensure you tick on Sync contacts and select OutLook in the drop down box.

Scroll to the bottom in the Advanced section, make sure you have, “Replace Information on this iPhone” for Contacts checked .

Click on Apply and it will Sync with your iPhone or iPod Touch. Now the Contacts on iPod will be deleted and replace with the Contacts on the OutLook in your computer.
