iPhone users and voicemail functions?

[karma]

Is there a way I can turn off my voicemail? I have an iPhone (not the new one) and I hate getting voicemails. Since I can do pretty much everything else, I was wondering if there is a way I can turn off the voicemail function where people can no longer leave a message...

Yes, call your service provider and have them disable that feature.
