I am using Apple iPhone 4 from past 1 month now, but I still have to figure out many function of Apple iPhone 4. I am having a long list of contacts and searching any through them all is hectic sometimes. So I wanted to know whether it is possible to make different categories for my contacts in iPhone. With having different categories the searching of contacts will be less painful and less time-consuming. Does anyone have got any solution regarding this issue of mine? Please help me with your suggestions.
