Hi Scotty,
I need to get my mobile me straightened out first..When I went from and Android to the IPhone my contracts multiplied so many times, I went from 2500 contacts to 17000!  What a pain in the neck!

You should be able to choose to find duplicates in Apple's address book.  Under "card" in the menu bar, select "look for duplicates".  Then select to merge duplicates as well as cards with the same name but different information.  At 17,000 it will take a while but Apple's address book usually does a very good job and fixing that problem.
