I would say this App is a life saver, couldn't imagine to find this App on the same day it has been released..
I was able to transfer my 1,600 contacts from Nokia to the iPhone perfectly..

The Outlook really bad for this, it doesn't copy more than 1 mobile for the same contacts, and I use to have 3 or 4 phone numbers of the type mobile for the same contact. The Outlook copies only 1 to the iPhone and ignore the rest.

But this App, just copied all the mobile numbers:
Read vCard for iPhone, iPod touch, and iPad on the iTunes App Store

However, make sure not to import your Contacts more than 1 time ! as then you will need to delete the duplicates manually. This App doesn't do Sync, it just import to the Contact.

I've benefit a lot from this forum, that's why I posted the useful App i've purchased to share with others..
