iPhone can sync contacts from google/exchange, or from an exchange server, or from Outlook via iTunes.
If you still have *any* winmo device you should be able to sync it to myphone, then sync it to outlook on the same machine you have iTunes on, and then sync from that to the iPhone.
Microsoft... not so open.
