Merge duplicate contacts on address book

It is really annoying have multiple sources of contacts on icloud such as facebook, exchange, your iphone/mac.

If you find yourself looking at your address book contacts and you can't decide which one is the right one between 3 or 4 duplicates, this suits for you:

• Go to your address book.
• On the top menu click on card menu
• Select "Look for duplicates"

After scanning your contact list, the app will ask you what do you want to do with the contacts (merge?)

That's it!
