I have a need for a contact manager, that will run on both a PC, and Iphones. So, a secretary can enter in a phone number and new contact, and a user can then see the contact on their Iphone. Is there a simple reliable app that everyone trusts? I don't want my contacts hijacked. If it cost, I Don't care. I want a $12 an hour person to be able to manage it, and not have to has an degree in computing to use it!
