Hello, I am currently looking for a solution for my business problem. I currently run a business that has 50+ 4S iphones, one for each of my employees. I want to create a global address book that includes all the phone numbers so they can call each other. At the same time I would love for the option to add or remove a contact to the global list as they leave or join my company. I have created a google account and was able to create this, however if a user deleted a contact on the phone then it deleted it off the global lists. Does anybody have a solution? I can't be the first one with this problem. Thank you!
