Changing voicemail on my Razr?

I bought a razr a year ago and I made a message with my friend. It's kind of stupid now because she talks and I don't so. How can I change the voicemail? I listened to all the options and can't find the one to change it. Can I have step by step instructions?Changing voicemail on my Razr?it depends on the carrier... with verizon you choose 4 for personal options and then choose administrative options and then greetings.. it should be somewhat similar with other carriers, if that doesn't work call customer service, they will be able to walk you through the prompts
