Hello how may I help you? Yes. I need to know about good management for my cellular phone contacts. I can do help! Okay. So, what do you recommend for proper classification of names of people I have saved. Try sorting by family and friends, and then coworkers. Great! Anything else you need help with? I recently tried to change a Mr. Smith to a Dr. Smith in my contacts. Can you help with that? Absolutely!.... and it's done! Great! What category would you give him? "Doctors"
