Question : Problem: Synchronising a public contacts folder to IPhone

Is there anyway we can force an IPhone to synchronise a public folder containing all our companys Clients numbers/email addresses etc, as well as syncing with their own contacts folder in outlook containing any personal contact records.
There must be a way of doing this but cannot see from searching the web so far.

Import them into active directory as contacts. If they are in your global address list, they will show up in iPhone.
