How to deal with DOUBLE contact list in iPhone?

[NJRonbo]

Had the iPhone 3G and currently a member of MobileMe.

Made a mistake when setting up my iPhone 3G S.

Instead of just letting MobileMe transfer my ADDRESS BOOK/CONTACT
information to my iPhone, I told iTunes to replace my contact list on
my iPhone.

Thus, I have two of every contact now.

How do I remove all the duplicates?

Thank you in advance!

In iTunes tell it to NOT sync any addresses, then on the phone go to your push settings for contacts and turn push off... then turn push back on. It will ask if you want to merge with current iphone contacts or replace. Tell it to merge. that fixed it for me.
