Wow super simple and solved my Exchange dilemma.

This was a great and simple option after researching for a few hours and trying a few other apps without any success. My issue was I had 3 accounts to merge on my iPhone:

1.My local iPhone accounts
2.My Hotmail account
3.My Exchange accounts (This was the major issue I had, as I was trying to find a app that allowed me to access the Exchange contacts as all my contacts were from my old company and they went out of business and removed the exchange server so I had no access to a live current PST file on Outlook. What I did have was a local cached version of my contacts on my iPhone that had been updated over the last 2 years with no easy way to get them off.)

I was able to deal with items 1 & 2 very easy. It was my Exchange account that was the challenge. After upgrading my Mac to Mountain lion I notice it synced and showed all my iPhone contacts on my Mac Address book after turning on iCloud. So I had item # 1. Then I downloaded a CSV file from my contacts in hotmail and imported them into my Mac Address book. I then turned off my Hotmail account contacts on my iPhone in the settings for this account so this took care of item #2. Then I purchased and download the “Air Contacts” and saw that it was showing me all contacts on my iPhone for all 3 accounts and allowed me to simply download a vcf file. So I went back into my iPhone and turned off iCloud. This then left me with just my Exchange contacts. I then ran the app, went to my browser and put in the address and created a vcf file to download with all my Exchange contacts into one file. I then imported the file to my Mac Address book, so now I had all contacts from my 3 accounts of 1500+ contacts in one place.
I simply went back to my iPhone and turned on my iCloud for contacts and all my contacts came synced back in. I then deleted my Exchange account on my iPhone to remove the duplicates and now life is GREAT! A HUGE THANK YOU to the Developer for this app. You solved my 2-year issue very simply. I cannot recommend this App enough!!!!!!!!!!
