Does anyone know of an app that will manage my native iphone contacts by allowing me to add b-days, wife name, kids names, etc? I want to be able to use it for tracking personal info about the person and also use it as a sales tracker. It would be nice to be able to add contacts to it that are not required to be in my iphone contact. I may not want to put one of my clients on my native phone contact since I may contact them thru their company, but I would like their name and personal info in a non native app so I can send cards or remember their spouses name. etc
