from experience, out of all the major carriers (att&t, verizon, mci, voicestream) sprint is by far the best! if you are currently with sprint and want a new phone just tell the customer service people that you want to cancel your service because you're interested in the motorola v phone and since sprint does not carry this phone, they'll offer you any of their phones free if you stay with their service. and for everyone whoe is thinking about using mci/worldcom as their carrier don't! they are the worst in everything!
